Chief CMA471 Large Plenum Enclosure for Chief Suspended Ceiling Kits (White)

The Chief CMA471 is a large storage enclosure that sits above ceiling tiles and pairs with Chief suspended ceiling kits. It gives installers a dedicated space for cables, power supplies, and compact AV devices above a standard 2 by 2 ceiling grid, keeping the room below clear and professional.

A hinged door swings open for straightforward servicing, and an interior panel supports two dual gang surface mount electrical boxes so power and data connections can live right next to the equipment. The housing has passed UL evaluation for use in air handling spaces, helping projects meet safety requirements. A finish in a neutral white color lets the enclosure blend with typical ceiling panels.

Weighing only 8.05 pounds, the unit is light enough for one person to lift into position, and it does not add significant load to the suspension system. Cable routing and maintenance are handled from below, reducing time on ladders during future upgrades. The enclosure is a practical choice for conference rooms, classrooms, healthcare suites, and retail spaces where clean appearance and reliable cable management matter.

The CMA471 works seamlessly with Chief kits CMS440, CMA440, CMA450, and CMA455, giving integrators the flexibility to match it to existing hardware. It measures 9.3 inches high by 14 inches wide by 7.8 inches deep, offering generous capacity without intruding on plenum space. TAA compliance supports government and enterprise projects that require it.
