Sometimes it happens that high -quality metal doors are equipped with a insulation layer, and the door itself is made of a strong steel frame of a certain thickness and a special brand. All this is the result of the fact that the door ultimately has a significant weight, which complicates the installation process. However, the mounting elements supplied by the plant very often turn out to be not very good quality. That is why, in order to make an additional strengthening of the structure, resort to the introduction of reinforced planks in the box. However, it is worth noting that not all doors need to be strengthened, so the Elbor front door is equipped with high -quality elements that prevent hacking and contributing to long operation.
Nevertheless, there are situations when the installation of such mounts in the already made holes in the box is not possible. To solve this problem, from the end of the design of the doors drill places for anchor bolts. Then the same thing is done on the opposite wall. The diameter of the drill in this case is selected equal to the diameter of the anchor. After installing the box, the holes are closed with decorative plugs.
