The Chief CMS491CP2 is a 1' 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-down carriage door gives full access to the equipment for service. It includes a dual-gang power housing with isolated ground and a duplex receptacle offering non-sacrificial, multi-stage filtering and surge protection. Chief rates it at 125 V~, 60 Hz, 15 A (1875 W continuous), with up to 40 dB of line-noise filtering and a Type 3 SPD rating. 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.
