The WB45S is a single surface-mount wall box from Audac for any 45 x 45 mm standard-sized module, such as Audac wall-mounted matrix control panels, volume controllers and connection plates. It is used where you cannot or do not want to cut into a wall, for example on brick or concrete walls, glass partitions, pillars, furniture or desks, so the control panel or input plate sits in a neat box on the surface. It comes with a metal subframe for fixing the 45 x 45 mm module. Audac also offers a double version (WB45D) and flush-mount boxes for solid (WB45S/FS) and hollow (WB45S/FG) walls. The box measures approximately 90 x 90 x 50 mm and weighs about 70 g. This is the white version (WB45S/W), which blends in with white painted walls in offices, classrooms, hotels and meeting rooms.
