Install the door box and door
Today we will tell you how to install a door box yourself. First lift the block and put a thick gasket under it. Although, probably, it will be better to put the door block on the mounting foam, which in recent years has replaced many improvised materials. It is important that the lower block is located horizontally.
You will need a level, as well as a plumb line and a square. It is necessary to control the position of the plumb line all the time so that it is in the center of the upper side and passes through the intersection point of the diagonals of your box. Check the lengths of the diagonals. If they are equal, then the box is exactly, without distortions. If not, then use the wedges for alignment.

Now everything is absolutely exactly. The next step is to fix it correctly. This is done at three points on each side. Opposite each side we make a hole in our wall. In them, then we will sew wooden traffic jams. And there we already drive the nails so that the hats fall into a tree two millimeters.
After the work done between the wall and the door box, the cracks remain, which are easier to close with mounting foam, which when expanding very well fills all free spaces.
