The Chief CMA473 Extra-Large Storage Box is the largest of Chief's above-tile enclosures for its CMA440 and CMS440 suspended ceiling kits. It installs directly over the column location on the kit, so cables can run from the stored equipment straight down through the column to the projector without being exposed in the room.
The box keeps a low 4.8-inch profile while stretching to 23.24 inches long, and a flat removable lid simplifies access in tight plenum spaces. Multiple knockouts in two sizes allow conduit and cable entry, and internal supports accept two dual-gang surface-mount electrical boxes. Chief states it is UL evaluated for use in air-handling spaces as defined by NEC Article 300.22(C) and lists it as TAA compliant. Finished in white; electrical boxes and equipment sold separately.
