Chief AV Storage Adapter for CMA473 & CMS440 Housing Units

The Chief CMSUNVU is an AV storage adapter that slips neatly inside CMA473 or CMS440 ceiling housings, turning unused space into a practical spot for small control processors, streaming players, or other low-voltage equipment. It gives installers a clean way to keep components out of sight while still leaving them easy to reach when service is needed.

Setup moves quickly because the adapter uses a quick-connect design with threaded thumb nuts. All required attachment hardware comes in the box, so there is no hunting for extra parts on site. Once mounted, the adapter holds gear firmly and keeps wiring tidy, which helps reduce call-backs caused by loose cables or shifting devices.

An open structure promotes steady airflow around the electronics, helping sensitive gear such as Crestron controllers run within the recommended temperature range. This focus on cooling adds long-term reliability to boardrooms, classrooms, and digital signage installations where equipment may stay powered all day.

The adapter is TAA compliant, so it satisfies federal procurement requirements for courthouses, military bases, or any public sector project that demands Trade Agreements Act adherence. Integrators working in government spaces can specify it with confidence.

Whether you are building a new collaborative space or retrofitting an existing ceiling box, the CMSUNVU offers a straightforward way to organize and protect valuable AV components.
