The Chief CMS491P2 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. 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.
