For the accuracy of the markings, a thicknesser is used. To do this, dilute the parts of the thicknesser to the thickness of the lock itself and make a measurement. Then the markings are transferred to the front side of the door. It is important not to forget to mark the place where the well will be located, and make a mark between the vertically arranged lines.

Drilling

Also, for a successful replacement of the mechanism, a drill is selected which will allow the spindle in the hole to rotate freely. A through hole is drilled using a drill mounted on the faceplate.
