For the manufacture of furnishings are used various elements connection of parts. Self-tapping screws are a popular type of fastener that has its own undeniable merits. Especially often they are used to assemble cabinet furniture, providing a solid and durable connection of parts of the structure.

Self-tapping screws are a popular type of fastener that has its undeniable advantages.

It is important to select fasteners based on the material and its density, thickness, etc.

Self-tapping screws have specific differences.

This type of fastener, like a self-tapping screw, is a type of metal screw with a screw thread and a pointed or flat end. The head of the element has a notch (straight, cross or polygonal) for twisting it into a canvas. For more quick connection parts of a cabinet or other object for elements with a sharp end, a screwdriver is used (in the absence of a screwdriver).

Also, the selection of self-tapping screws is influenced by the type of construction and the desired appearance products.

Due to the thread, the screw is easily screwed into wood panel or chipboard. For concealed fastening furniture parts, an eccentric screed is used, in which self-tapping screws play a major role. As a result of this type of assembly, tables or other objects are neat, without external traces of installation that spoil the appearance of the product.

This type of fastener, like a self-tapping screw, is a type of metal screw with a screw thread and a pointed or flat end.

Important! The length of the screws can reach up to 50 mm and above. Such fasteners are intended for thick solid wood panels.

Self-tapping screws are used for fixing parts without prepared holes or with them.

The appearance of the product is affected by the possibility of installing a hidden connection.

Depending on the material and design details, there are two types of fasteners:

• with a rare carving and a sharp end;
• confirmations.

Due to the thread, the screw is easily screwed into a wooden panel or chipboard.

The first type is used for solid wood, chipboard, chipboard and MDF. May vary in length and diameter.

For your information. To assemble narrow canvases and plywood, short screws are used.

The length of the screws can reach up to 50 mm and above.

The second is used for the manufacture of furniture mainly from wooden planks sufficient width. It differs in that at the junction of the thread and the smooth upper part, a thickening begins on it. Confirmates often have a flat end and therefore require prepared holes.

• distortion of parts;
• loosening of fastening with repeated screwing.

The base of the screws is steel.

How to choose?

When buying self-tapping screws, it is important to consider many points. The base of the screws is steel. To connect specific parts, elements with different coating. When assembling furniture, you must consider:

• length of fasteners;
• their diameter;
• cap thickness;
• carving;
• degree of corrosion (depending on the coating).

To connect specific parts, elements with different coatings are used.

Also, the type of construction and the desired appearance of the product affect the selection of self-tapping screws.

The color of the fasteners is also important when open connection. In this case, it is worth choosing elements to match the canvas.

An indispensable component of cabinet furniture is a connecting fitting - a coupler. Furniture screed, as a rule, invisible on the product, is the key to the durability and strength of cabinet furniture.

Historical digression

The first "connections" used to strengthen furniture were universal - they were used both in the construction of structures from timber, such as a church or a hut, and in the manufacture of furniture.

Masterfully wielding a saw and a chisel, carpenters manually made elements of a furniture coupler, among which the key joints, wedges, spikes, and “shkans” (in modern version- dowels).

The process was quite labor intensive. Details provided a screed only with a tight connection with glue and an absolutely perfect fit to the product. These compounds are currently applicable only as a decorative element in the manufacture of furniture in the "retro" style, due to giving a resemblance to furniture made by craftsmen.

Since the time of carpentry, only a dowel (8 X30), a modernized look, has remained in use.

All other developments of artisans gave way to a specialized furniture screed.

So the dowel received a corrugation and a precise chamfer at the end on both sides. Assembling furniture using a dowel allows you to quickly and correctly position the parts of cabinet furniture during assembly.

At the same time, the dowel is a simple and cheap part, it is the small costs that make the dowel stand out among the many special fittings.

The dowel takes on lateral loads and prevents displacement individual parts cabinet furniture during operation.

But, working with dowel also has its difficulties and disadvantages. For example, when making a dowel from undried wood or inappropriate storage (high room humidity), the dowel can change its cylindrical shape, which will make it impossible to form a high-quality joint.

At big size products and, accordingly, increasing loads on the joints, dowels are not able to resist pulling out and need additional reinforcement of the product - a furniture screed.

Types of furniture ties

The main types of screed actively used by furniture manufacturers are:

• Using a barrel tie or screw tie
• The use of a conical screed
• Application furniture corner
• Application euroscrew or screw tie
• Application eccentric brace

The listed types of screeds have different principle work, as well as the advantages and disadvantages characterized by the product from a positive or negative side.

Screw coupler: principle of operation

The considered type of screed contains two elements: a screw and a "barrel" - a screed body made in the form of a cylindrical part with transverse threaded holes.

"Keg" is made of metal or polymer material(plastic) with a nut inside. A "barrel" made of polymeric material has a larger diameter compared to a metal product.

The main advantages of a screw tie include high strength and a large stroke of the tie, since tightening the screw with considerable effort provides a strong coupling under transverse loads.

With the indicated advantages of using a barrel screed, one should not forget about the disadvantages of this type of furniture fittings.

First of all, this is a complicated assembly, since the hole in the housing must be correctly and accurately aligned with the screw.

As a result, the mutually located axes of the holes for the screed body and the screw must ideally intersect in the face and end.

If the installed housing is simply turned on the wrong side, it will not be particularly difficult to turn it into the correct position using the slot on the end provided for such cases.

However, if the hole for the "keg" is deeper than required, the case will simply "sink" and it will be extremely difficult to pull it out of the recess.

Another disadvantage of the screed is the screw heads visible on the side surfaces of the furniture, which spoils the appearance of the product.

Even if the screw head is covered with a plastic plug, it will attract attention and general form will be damaged, since the plug has a convex appearance and does not always correspond to color scheme with the product.

The use of a conical screed: the principle of operation

In order to improve the appearance of the furniture, the “barrel” coupler was modernized, which made it possible to hide the screw, since it was replaced by a rod pressed flush into the face of the cabinet furniture element.

So, in the main part, it is necessary to drill two holes - at the end for the rod and in the face, perpendicular to the first hole, for the barrel.

A rod with a conical recess is installed in the transverse opening of the body. The tip of the screw also has a conical shape and rests against side surface screed rod, shifting it to the end of the main part, which allows you to achieve the optimal voltage for the screed.

The disadvantages of the conical screed include high requirements for the accuracy of the location of holes in the elements of cabinet furniture, a small tightening stroke, and the complexity of assembly.

Moreover, under significant loads, it is possible to crush the edge of the coupling hole, which makes the tie inoperative as a whole.

Furniture corner: the principle of operation

It is a strip of metal bent at a right angle with a hole and a groove on opposite shoulders.

Includes five elements: angle, two countersunk screws, two threaded bushings. The corner is attached to furniture parts using futorok with internal thread.

This tie is strong and easy to install and does not require precisely positioned filler holes. The main disadvantages include a large number of defects in manufacturing, inconvenience in operation (it is impossible to place objects directly against the wall of the product) and the visibility of the screed, which spoils the appearance.

Euroscrew: principle of operation

Euroscrew came into use with domestic furniture makers in 1973. Then the screed had the name "Confirmat" and was presented in the "Hettich" catalog.

In Europe, this screed is called "Einteilferbinder", which means single-element or single screed.

For some reason, domestic furniture assemblers gave it the name "euro-screw" or "euro-screed", while in fact it is a "screw screed" due to the similarity of the case to a blunt screw.

Today, euroscrews are not only imported from abroad (“Hettich” - “Direkta 2”, “Dresselhaus” - “Unita Stahl”), but are also produced at domestic enterprises.

The Euroscrew was widely used due to the fact that it does not imply the presence of accuracy during its landing.

It is only necessary to drill two holes: the first - in the end face of the body, the second - in the plate attached to it.

Euroscrew is designed for screed small furniture, while different manufacturers endow screw ties with special design features.

The use of a screw tie does not imply countersinking of the hole. The small diameter of the screw head allows you to recess the elements of the tie flush with the surface of the part to be joined.

Also, in a screw tie, it is common to use a body with a provided “tooth” under the screw head, which ensures flush without the need for a countersinking procedure, when forming a hole chamfer.

A high-quality screed should not have displacements of the slot or cap relative to the axis. If the displacement still takes place, the strength and functionality of the connection of furniture parts from chipboard deteriorates.

For a more durable connection of parts, it is necessary to use a coupler with a small pitch of turns and with a better threaded sharpness. The first threads are conical with special notches, which characterizes the work of the coupler in the form of a tap or self-tapping screw.

Tapered turns, and there are mainly four of them, ensure that high-quality threads are cut to accommodate the remaining turns without disturbing the structure of the plate.

The disadvantages of the screw tie include visibility from the end of the screw head. It is usually, as in a screed-barrel, closed with a polymer plug.

Furniture assembled using this tie cannot be assembled more than three times, as the thread breaks. Refusal to use the dowel during work is the reason for the deterioration of the appearance of the furniture.

Relying on the strength of the metal components of the screed, the elements in the lease are not fixed, which “takes away” individual parts of the furniture.

Eccentric coupler: principle of operation

Eccentric screed occupies a leading position among these types of screed, displacing even a screw screed. The highest quality cabinet furniture is assembled using an eccentric tie.

The principle of operation of the screed is quite straightforward.

A metal or polymer futorka is screwed flush or pressed into the surface of the attached web, then a tie rod is screwed into it, the head of which has a "T"-shaped shape.

When assembling furniture, the rod must pass through the prepared hole in the end of the key part, which will allow its head to be in the center of the transverse hole drilled in the plate.

Turning the eccentric in the hole creates an effect on the head of the rod necessary for the convergence of the parts to be joined and the optimal force in the connection.

The eccentric coupler includes such elements as: cast metal eccentric, futorka, rod.

The designs of the eccentric coupler are widespread, characterized by the direct screwing of the rod into the material of the part to be tightened, without the use of a futor.

The main difference between eccentric couplers of various manufacturers and designs lies in the use of eccentric of different diameters.

Mostly used eccentrics having diameters of 12, 15 and 25 millimeters. Eccentrics with a diameter of 25 mm are necessarily covered with a plug made of polymeric material.

Disadvantages of an eccentric screed:

1. High probability of screed loosening during operation finished product. Different manufacturers solve this problem in different ways. So it can be a concave inner surface of the eccentric in contact with the spherical working surface of the stem head. Some manufacturers use base designs in which the multi-stage inner surface of the eccentric is adjacent to the flat working surface of the rod head. When using a multi-stage eccentric, its outer surface is provided with oblique smoothed teeth, which are inclined in the opposite direction relative to the direction of rotation of the eccentric during assembly to increase the adhesion force with the material of the parts, and also prevent spontaneous rotation and loosening of the connection during the use of cabinet furniture. The notches applied on the inner surface of the eccentric increase its adhesion to the stem many times over in comparison with the use of an eccentric with a smooth working surface.

2. Requires accurately measured relative position of all holes. The lack of precise additive equipment hinders more and more widespread use of an eccentric screed. So, drilling parallel holes "on the knee" leads to breakage of the eccentric even with a small effort during assembly. These shortcomings, although negatively affecting the growth in the use of eccentric screeds, do not prevent the introduction of more and more easy-to-use types of screeds. For example, when using the most common eccentrics having a diameter of 15 mm, they can be of different lengths in order to be located exactly in the center of the web of the hole for the rod.

Varieties of eccentric couplers:

• reinforced eccentric
• reinforced eccentric with additional futorka

One of the ways that allows you to move away from the complicated alignment of the axes of the holes in the end face and the face of the product can be considered the use of eccentrics directly in the body.

The eccentric is installed in a hole prepared by drilling in the plate near the end of the web, forming an opening for the exit of the eccentric body part with a hole for the rod.

This method allows the use of a shorter tie rod, allowing the eccentric shaft to be placed closer to the end face of the key piece.

Due to the design features of the reinforced eccentric, the coupler can be tightened by placing the screwdriver at an angle to the details of cabinet furniture. The outer body of the tie with the use of a reinforced eccentric can be made of plastic of various colors or metal, which of course will give a more attractive look to the furniture.

The tie is widely used as a shelf holder. Unlike shelves installed on conventional shelf supports, a shelf using a coupler based on a reinforced eccentric allows you to create a structural strength element to increase the strength of the finished product, which is the main characteristic when choosing cabinet furniture and office furniture.

The eccentric is necessarily placed in the material of the body, and not in the canvas of the shelf, which allows you to repeatedly rearrange the shelves without loosening the connection and wearing out the hole with the eccentric.

A reinforced type eccentric with an additional bushing is used for products that are especially loaded or subject to high loads.

In the case of heavy shelves, a reinforced type eccentric in an elongated body is used, which has an additional stopper, under which an additional hole is provided. The applied futorka allows to stabilize the shelf, preventing its displacement relative to the sidewall.

The article discusses the most common types of ties for connecting cabinet furniture parts. The above advantages and disadvantages of certain screeds will allow you to choose the most acceptable screed option, and avoid common mistakes.

The full range of ties used for cabinet furniture in this company can be found in the electronic catalog or in the company's office.

When choosing a screed, you should understand that it is not just a significant connecting element of cabinet furniture, but a device that allows you to create the necessary force between the parts to increase the resistance of furniture to external loads, creating the necessary strength for its long-term use.

All generations of furniture ties. Start

Connecting fittings- the most important component of cabinet furniture, therefore, an inconspicuous, as a rule, screed has become today one of the main elements of furniture, ensuring its strength and durability.

The history of the "connection"

In ancient times, furniture making did not differ much from carpentry. When connecting its parts, the same techniques and methods were used as in the construction of a hut or church: lock joints, spikes, "shkans" (now - dowels) and wedges that gave strength to benches and tables. To make such connections manually is a rather laborious task. The parts were held together by a tight mutual connection with glue, the accuracy of which was ensured by eye, and it was necessary to masterfully use a saw and a chisel so that they fit exactly to each other. Similar compounds can still be found in antique-styled furniture, but rather, as decorative element, which makes furniture in the "retro" style only look like it was made by the hands of experienced craftsmen.

Since that time, only dowels(8X30), however, also acquired other sizes, received corrugation and a precise chamfer at the ends. Everything else has given way to special fittings. The connection of furniture on dowels even now gives us the opportunity to quickly and correctly position furniture parts during assembly, and prevents their mutual displacement during operation, perceiving all transverse loads. Shkant - very cheap and simple detail, but it also has its own difficulties. It is produced from natural wood and when made from uncured wood or with improper storage, it is able to change its cylindrical shape, which significantly affects the quality of the connection. However, on the dowels alone, furniture of small dimensions is connected. With large sizes of products and correspondingly increasing loads, dowels can no longer withstand pulling out, that is, longitudinal forces, and therefore, ties can always be found next to them. |

Types of screeds

Corner tie UC11

Principle of operation:

The product is also very simple in design: a strip of metal bent at a right angle with a hole on one of its shoulders, and a groove on the other. Completely it consists of five elements: a corner, two screws with countersunk heads and two threaded fittings. During assembly, the angle is fastened with screws to the parts to be joined using metal or plastic fittings with an internal threaded hole. The tightening force is achieved by shifting the axis of the mounting hole on one of the parts to be joined. As a result, when screwing the screw, it presses with the cone of its head on the conical side surface of the hole in the corner, displacing the entire attached part and attracting it.

Advantages:

At one time, this screed even received predominant distribution in our industry, since:

• durable;
• does not require drilling holes in the ends;
• easy to install;
• unpretentious to the accuracy of the location of the filler holes;

Some furniture makers even managed to use such a screed without any dowels in the joint!

Flaws:

• visible;
• interferes with the operation of furniture (for example, it will not be possible to put a box in a closet close to its wall, and taking it out, it can be torn or scratched;
• a lot of marriage in its manufacture;

As for attempts to use metal or plastic corners fixed with screws to connect furniture parts, it is better not to buy furniture with such connections: this is not a screed at all, and you will get a reliable tension gusset in any furniture with their help it is impossible.

Screw tie KON 7x50 (Euroscrew)

Story:

This screed became known to domestic furniture makers back in 1973 from the catalog "Der Grosse Hafele" under the name " Confirmat". It has always been intended only for the assembly of small-sized furniture. Today it can be found in the same catalog, under the same name. But today, many companies produce the same ties: "Hettich" ("Direkta 2"), "Dresselhaus" (" Unita Stahl"), etc., and even domestic enterprises.

In Europe, this screed is called " Einteilferbinder" or " single-element screed (single)". And for some reason we call it " euro screw" or " euroscrew". Although the name would be much more suitable for her." screw tie", especially since it looks like two drops of water like a screw, only thick and blunt.

Principle of operation:

The simplest screed, which has found such widespread use among our furniture makers precisely because it does not require almost any accuracy at all when adding. Only two holes are drilled: one is at the end of the main part, the other is in the plate attached to it.

The most popular are euro screws with a thread diameter of 7 mm and a length of 50 or 70 mm. Screeds different manufacturers have their design features. The small diameter of the cap often allows, by applying force, to flush the screed with the surface of the slab without first countersinking the hole. Also, screw ties can have a specially provided "tooth" under the head, similar to a flash in a poorly made nail, which ensures that it is screwed flush without countersinking, forming a chamfer of the hole.

A high-quality screed should not have a head or slot offset relative to the axis. If this alignment is not present, then the screed will go uneven when screwed in, and the thread will break the hole, which worsens the strength of the connection of chipboard parts. A coupler with a smaller pitch of turns and with a greater taper of the thread provides a stronger connection. The first four threads are conical and have special serrations. Therefore, the coupler works like a tap or a self-tapping screw, ensuring that even, high-quality threads are cut to accommodate the remaining turns without disturbing the structure of the plate.

Flaws:

• head visible from the end. It is usually closed with a plug;
• furniture assembled on such a screed cannot be assembled more than three times, since the threads cut in such soft material like chipboard is likely to break. The trouble is that many manufacturers, rightly hoping for the strength of the metal, stopped using dowels altogether with this screed. But if the assembly is carried out without fixing the parts in the clamp, then the parts can "take away", which can be noticeable when examining some products;

5. Eccentric coupler(EC02 + Stem (TE 03) + Futor (BU 01))

Despite the popularity of screw ties, all the highest quality modern furniture assembled using eccentric couplers.

Principle of operation:

A metal or plastic sleeve is screwed or pressed into the face of the attached part flush with it, into which the tie rod with "T" is screwed - shaped head. When assembling the product, the rod passes through the hole in the end of the main part, and its head is in the middle of the transverse hole drilled in its face. An eccentric is installed in it, capturing the head of the rod with its inner eccentric surface. With further rotation, the eccentric, turning in its hole and acting on the head of the rod, first brings the parts to be joined together, and then creates the necessary force in the connection.

The eccentric coupler consists of a cast metal eccentric, a futor and a stem. There are also quite a few designs of such couplers, in which the stem is wrapped directly in the material of the attached part, without the use of a futor. The main difference between eccentric couplers from each other is the diameter of the eccentric. The larger it is, the greater the stroke of the screed and the greater the possible force. Eccentrics with a diameter of 25, 15 and 12 mm are used. Eccentrics with a diameter of 25 mm, and sometimes 15 mm, must be closed with a plastic plug.

Flaws:

• possible weakening of the screed during operation of the product. Different manufacturers solve this problem in different ways. Some zip ties have an internal working surface the eccentric is made concave, and the spherical working surface of the rod head is in contact with it. In other designs, the inner working surface of the eccentric is stepped, and the working surface of the rod head adjacent to it is flat. At the same time, the outer surface of the eccentric is provided with oblique smoothed teeth inclined in the direction opposite to the direction of its rotation during assembly, which, increasing adhesion to the material of the part, additionally prevents its spontaneous rotation and loosening of the connection during the operation of the product. Also, the notches inside the eccentric increase its grip on the stem by three times, compared to a smooth flat surface;
• An eccentric tie requires extremely accurate relative positioning of all mating holes. Drilling these holes "on the knee" will often cause the eccentric to break when the assembly force is applied. Actually, the lack of precise filler equipment limits the widespread use of eccentric couplers in domestic furniture;

Varieties of eccentric couplers:

There are many varieties of eccentric couplers designed to solve various tasks. For example, with the same, most common diameter of 15 mm, the eccentric can have a different height so that, regardless of the thickness of the part, the hole for the rod can be located exactly in the middle of its thickness. And this makes it possible to provide a smaller number of standard sizes of parts when adding.

One way to get away from the complex alignment of the axes of the holes in the face and end is to use eccentrics in the body (SE 01 + stem (TI 04)). The eccentric is installed in a hole drilled in the plate near the end of the part, so that an opening is formed in the end of the part, where a part of the eccentric body with a hole for the stem comes out. In this case, the tie rod is shorter, and the eccentric axis is located closer to the end of the main part, but due to the design features, the tie can be tightened by placing the screwdriver at an angle to the plate. The outer casings of these ties are made of plastic. different colors, or metal (a more expensive and beautiful option).

This screed has found its application as a shelf holder. But, unlike inset shelves installed on conventional shelf supports, shelves using such eccentric couplers are always a structural element, which increases the strength and rigidity of the entire product, and this is especially important for a heavily loaded office furniture. The eccentric is placed in the body material, which is stronger than the plate from which the furniture is made. Therefore, repeated rearrangement of the shelves does not lead to wear of the eccentric hole and loosening of the connection.

Reinforced eccentric with extra sleeve SE07

For particularly loaded, heavy shelves, there is a reinforced eccentric in an elongated body with an additional foot (SE 07), for which a separate hole is provided. Such a screed is even better retained in the chipboard, moreover, the futorka stabilizes the shelf, preventing it from moving relative to the sidewall.

Conclusions:

The article discusses only the main types of ties for connecting furniture parts. You can familiarize yourself with the full range of MDM-Komplekt furniture ties in the electronic catalog or in the office. The main thing when choosing a screed is to understand that it is not just a connecting element in furniture, but a mechanism that creates a force between the parts, due to which the furniture acquires resistance to external loads and the necessary strength.

Yours, Fedor Konfirmatov

After the assembly of cabinet furniture, some parts of the structure may have a slight skew relative to each other. If you do not connect individual cabinets or cabinets kitchen set among themselves, it will look sloppy and inharmonious. Fasten securely individual elements will help screed furniture intersectional. Thanks to this fastener, cabinet furniture looks like a single structure.

Furniture intersection screed - best way connections between individual modules. Home craftsmen use self-tapping screws to fasten the walls of the headset. It is better not to do this: under the weight of the structure, the screws can tear out and the appearance will be spoiled.

The coupler consists of a cylindrical nut with an internal thread and a screw. Hardware is often chrome-plated, they are not subject to corrosion. This is especially true if the furniture is in a room with high humidity. On the nut, for reliable fixation of structures, there are slots. An intersectional screed for furniture should be installed without overtightening the fasteners, since if screwed in hard, the nut or screw head can deform the furniture walls.

It is better to put wide washers under the nut and screw. They will help to tighten the screed as tightly as possible, while not damaging the polish. So that the screed does not stick out from inside furniture, countersinking is necessary. This is not a difficult process, so you can do it yourself.

Manufacturing materials

Ties for connecting two parallel cabinet walls are produced from:

• Nickel-plated steel;
• Galvanized steel;
• Chromed steel.

Chrome plated

galvanized

Dimensions may vary: M4-M6, screw length L1 - 15-30 mm, length L2 - 10-15 mm, outer diameter 5-8 mm. It should be noted that for many years of using various fasteners, intersection fasteners are the most optimal when connecting headset modules to each other. It allows not only to perfectly fasten the structure, but also facilitates the process of assembling furniture. This fastener has an attractive appearance due to the anti-corrosion coating.

Sometimes you can meet plastic construction clamps with metal screws. Its dimensions do not differ from metal counterparts, but it is less reliable in everyday use.

Installation rules

Intersectional screed furniture is made using clamps. The use of this tool helps to tightly connect upright, parallel walls of furniture to each other. Installation is carried out as follows:

• Install cabinet furniture;
• Fix the walls with clamps. If we are talking about small kitchen tables, then only 2 tools can be used - the clamps must be at the top and bottom of the structure;
• At a distance of ten centimeters from the corners, mark and drill holes, the dimensions of which will correspond to the diameter of the screed;
• Install a nut in the hole;
• Start tightening the bolt, trying to make the mount tight, but not overtighten;
• Perform countersinking. Have to take special tool- a countersink and drill a recess for the screw head. The procedure can also be performed using a thick drill, which needs to slightly expand the edge of the inlet.

If the nut begins to turn during the screwing process, then it must be fixed with a second Phillips screwdriver. The intersection screed will stand out on the surface, but this in no way spoils the appearance of the furniture. If protruding heads are not to your liking, then you can use special plastic pads or decorative caps.

Experts advise using a screed to evenly connect the front side of the walls if the furniture is on an uneven floor or against a curved wall. If in this situation the back of the furniture is left free, then it is possible to compensate for uneven surfaces. To determine exactly how far from the end to install the screed, pay attention to the depth of the connected walls.

Ideally, the location of the fasteners looks like this:

• The upper sections are fastened only on the front side, two ties are installed there at a distance of 10-15 cm from the edge;
• The lower sections are fastened with three structures, two of which are located on the front side, and one on the back. Moreover, the latter is located in the middle of the wall.

If the fasteners are installed correctly, then after hanging the doors during the final assembly, they will not need to be adjusted. As you can see, the intersection screed is essential. If the set consists of several cabinets or cabinets that cannot be leveled due to uneven surfaces, this trouble can be compensated by applying this species ties for furniture. But keep in mind that only the front surface of the walls of the headset is pulled together.
