In order not to invite a specialist who knows how to adjust the hinges for metal doors and save money, it is worth familiar with the following recommendations. This will allow you to work yourself. Adjusting metal doors loops does not require special skills and applying complex tools.

What are the loops of the entrance doors

For the manufacture of loops, carbon and stainless steel are used. In some cases, steel and brass alloy with chromium spraying (more expensive). Door hinges for metal doors in their design door hinges can be divided into:

• loop groups with support bearings;
• loop with a support ball;
• hidden type;
• classic.

Classic is the simplest, cheap and quickly wearing. Modern doors are rarely equipped with them, but the loops of this type are still found. Hidden loops for metal doors have a high degree of antszlocity. The loops with supporting bearings and the ball have the longest service life: carbide metal of rubbing parts wear more slowly than ordinary carbon steel. In addition, during their operation, the backlash and creak are excluded.

How to adjust the metal door loops: classic option

During operation, the door loops experience heavy loads, which leads to their wear. To a certain extent, such wear can be compensated by adjustment, for which the following should be performed.

1. If the loops are not welded to the canvas and the door of the door, but are fixed on the screws, you should replace them. Under the load, they deform, as a result of which the door sends. To replace, you need to find screws made of carbide metal.
2. In the event that the loops are just creaked a little, you can lubricate them, slightly raising the door with scrap, using them as a lever. The wD-40 smear is also effective: a small amount of fluid will eliminate the creaking.
3. If there are explicit traces of the production of washers on the rod, it should be replaced. This operation will require the participation of several people with a tool. The door is removed from the loops, clean the old washer, then rub the rod and its nest, cleaning from dust and metal chips.
4. The scene is installed in the place of the erased washer, mandatory from carbide metal. It should be a little thicker than the previous one (taking into account the production). You can install engraver instead of the washer instead of the washer: it will be absorbed and reduced the load on the lower part of the loop.
5. The loop can be slightly upgraded: it should be drilled in the upper part sang through a hole. Through it, periodically during operation it will be possible to fill the machine oil using a syringe.
6. The loop rod must be lubricated with a thick lubricant, such as "Litol" and join the door again.
7. You should try the work of the loop, by opening several times and closing the door. In the event that the friction of the box can be friction, it is necessary to eliminate it with an additional washer or replacement already installed on a smaller thickness.

How to regulate metal doors with inner loops

In the first place according to the degree of protection against hacking, there are hidden loops for metal doors. Their price is higher than those of classic, but expenses are justified by high reliability. Internal hinges for metal doors are adjustable and non-regulated. The latter in the event of a failure will have to be replaced, so it is better to choose metal doors with hidden loops that can be adjusted. This is performed as follows.

1. To change the angle of installation of the door leaf vertically, it is necessary to shift the loop to the left or right. We should weaken the extreme upper and extreme lower protracted screws. After - neighboring (they are located on the same line). This requires to use a six-sided key of 4 mm. Screws are rotated 180 ° counterclockwise.
2. Also counterclockwise, the in-depth screws are rotated, located in the upper and lower end pieces of the loop. You can see them if you look at the loop from above.
3. The central adjusting screw is dragged, so that the door is attracted (the gap between the web and the box decreases). If weaken the screw, the door will be the opposite - "depart" from the box.
4. After adjusting the position of the door leaf, the protracted screws are delayed in the same sequence, which weakened them.
5. In order to change the height of the installation of the canvas, you need to weaken the same screws (installed in the end of the loop), which are indicated in clause 1.
6. Weakening the lower end screw and tightening the top, the door canvas are lowered, and on the contrary, weakening the upper screw and tightening the lower - raise. After adjustment, all weakened screws are tightened, but not applying excessive efforts (so as not to disrupt the position of the web).
7. The secret hinges for metal doors should be purged, cleaning from dust and lubricate with machine oil, injecting it between rubbing surfaces with the help of ancoal or medical syringe.

Loop adjustment with support ball or with bearings

The loop of this type is adjusted by the screw located at the top. When screwing the screw, the lower part of it will rest in the ball (or pin of the loop of the loop) and lift the door canvas. This must be done as metal abrasion.
Having twisted the screw completely, you can lubricate the loop mechanism through the hole, after which the screw is returned to the place. In this way, you can correctly install the door leaf and reduce the load on the loops and the shutters. Such a procedure should be carried out periodically, since as a result, the loop adjustment is broken.
