The Chief CMA474 SYSAU Above Suspended Ceiling Storage Box is a scalable equipment enclosure built exclusively for Chief's SYS Suspended Ceiling Projector System. Its width adjusts from 12 inches collapsed to 22 inches expanded, so it can grow to fit the AV gear you need to hide, and it shifts along the system's tile bridge to work around ducts, sprinklers and other obstructions.
Removable covers allow side access when the plenum is shallow or full top access when there is room above. Six trade-size conduit knockouts (0.5, 1 and 1.5 inch) handle power and signal entry, and flexible knockouts let high-voltage conduit enter when power faces the room below. Chief rates it for 35 lbs, lists it as UL evaluated for air-handling spaces under NEC Article 300.22(C), and as TAA compliant. It is not compatible with Chief's CMA440/CMS440 kits.
