System covering made of 2.5 mm thick Bakelite. This covering can be combined with all junction boxes, dimmers and special devices (thermostats, USB charging stations) from the Bakelite switch system and is intended as the centre part of a multi-part installation. System coverings can be installed flush next to and below each other.
Switches, push-buttons and sockets only fit into the regular coverings. Round and square single coverings are also available.
