The 2N 9155067 is a 3 (w) x 3 (h) module backplate that enables a 2N IP Verso intercom to be installed on virtually any uneven surface, including glass.
It provides a secure, level mounting base where a standard surface or flush installation would not be suitable.
Ideal for apartment complexes, offices, schools and public buildings where the intercom must be fitted to non-standard surfaces.
