Product Overview
The Chief CMSUNV2 adds an extra shelf to the CMS492 2-foot by 2-foot above-ceiling storage box. It expands component capacity for AV gear concealed in suspended-ceiling installations. The shelf is a direct accessory for commercial AV and digital signage projects using the CMS492 enclosure.
Product Description

The CMSUNV2 can be ordered to add an additional shelf to the CMS492 2-foot by 2-foot storage box, increasing the amount of AV equipment a single above-ceiling enclosure can hold. It mounts inside the CMS492 to create a second tier of component storage, which helps integrators keep concealed gear organized and serviceable. The shelf uses quick connect and disconnect threaded thumb nuts, so it installs and removes by hand without tools for easy access during service calls. As a Chief accessory, it is matched specifically to the CMS492 enclosure for a precise fit. The CMSUNV2 is TAA compliant, supporting specification in government space and other procurement-controlled environments. It is the straightforward way to expand storage capacity within an existing CMS492 ceiling box.
