Mounting plate offset for 2 wall plates

Offset mounting plate for the inside micrometers 73, 80, 100 and 153 mm. It simplifies the installation of SilverTec® wall plates in the masonry.
The tabs of the metal plate are fixed on the wall surface directly next to the area knocked open and this results in a fixed installation depth of the wall plates to be mounted on the metal plate. The depth of the opened area can, therefore, be rough as long as it is deeper than the installation depth of the metal plate. This saves time during the installation.
