To use the Berker 91820, first ensure the wall cavity is prepared to the correct depth and dimensions. Insert the box into the wall opening and secure it firmly using appropriate mounting hardware. Once the box is stable, route the electrical cables through the designated entry points before connecting your switches or sockets.
