Metal Back Box
MBX back boxes can be used in walls or ceilings where a UL rated metal enclosure is required behind the speaker or to reduce sound transfer to adjacent spaces. At 3-1/2” (89 mm) deep, the MBX series of back boxes will fit into standard 2×4 stud bays or larger apertures and are designed to fit in between 16” (406 mm) on-center studs.
MBX metal back boxes are constructed of 1.1 mm thick metal, are UL listed, and shipped fully assembled. Convenient knockouts for conduit are provided, 2 each on the top and bottom of the box. The knockouts will accept either 1/2” (13 mm) or 3/4” (19 mm) conduits and loom clamps.
