The network socket is however quite bulky on the back, when installed in a flush-mounted box this probably should if possible be empty (was with me unfortunately not the case, could the network can therefore not quite justified "sink"; no matter, is behind a dresser hidden, not visible).
Very important: be sure to use a matching "lay-on tool" for installation - Pfenningkram if not order exists necessarily. With this tool, the installation is extremely simple, clean and safe, without the would become a miserable stocherei with screwdriver / knife / etc.
