It is no secret that the necessary insulation layer includes the set of high -quality metal doors, and the manufacture of the door frame is carried out using a special brand of steel and an enhanced frame. This feature of the production process is very often the result of a large weight of the structure, and this, in turn, complicates the installation. However, the fasteners provided by the plant often turn out to be not quite excellent quality, as a result of which there is a need to perform additional strengthening, for which additional planks are placed in the box. Nevertheless, not always any door requires strengthening, for example, the Elbor luxury door is equipped with high -quality fittings and elements that contribute to long service and prevent hacking.
In some cases, a situation may arise in which holes are made in the box, but it is not possible to install fasteners. To solve this problem, you will need to drill holes for attaching anchors from the end of the box. Similar holes are made on the wall. The drill for this task is selected taking into account the diameter of the anchor bolt itself. Upon completion of the installation, with decorative plugs, close the holes made.
