The Chief CMS492 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. 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.
