The Chief CMS492C is a 2' x 2' enclosure that installs in a suspended ceiling grid and hides AV equipment such as switchers, extenders, amplifiers or network gear above the tile, keeping classrooms and conference rooms free of visible boxes and cable clutter. It also provides a 1.5-inch NPT column drop, so a projector can hang from the same tile grid, with pipe position adjustable to reduce reliance on image correction. A drop carriage door gives full access to the equipment for service. A detachable power housing can be pre-installed by the electrician and attached to the box later; it accepts up to two single-gang or one dual-gang outlet facing into the box or the room, with four nested knockouts for 1-1/4", 1" and 1/2" conduit. The AV tray ships with one shelf, and total capacity is 100 lbs (45 kg): 50 lbs for the projector ceiling plate and 25 lbs per shelf location. Speed-Connect installation hardware is included, and the lightweight build allows one-person installation. The box is UL evaluated for air-handling spaces per NEC Article 300.22(C) and TAA compliant.
