Suspended Ceiling Kit

The Chief Manufacturing CMA450 is a 2' x 2' plate designed to sit above a suspended ceiling tile and remain unseen. It is secured by a safety wire and provides nine mounting hole positions with threaded ends that accept 1 1/2" NPT extension columns. This accessory suits installers who need flexible projector positioning within a standard grid system.

Installers using standard grid ceilings

The kit fits professionals mounting projectors in drop-ceiling environments where a secure, hidden anchor point is required. It is not intended for surface-mount installations on solid drywall or concrete soffits. Buyers who need a visible flush mount or a direct structural attachment should look at a different mounting style.

Nine mounting hole positions

The plate offers nine threaded mounting locations for the extension column, allowing the projector to be positioned precisely within the ceiling tile footprint. This flexibility helps align the lens with the screen without cutting additional holes in the grid. The hole pattern is the specification that determines whether the kit matches the required throw offset.

Questions about this item

Will the CMA450 add any fan noise or heat to a ceiling cavity that runs continuously?

The CMA450 is a passive 2' x 2' ceiling plate with no moving parts or electronics, so it produces zero noise and no heat during all-day operation.

What existing ceiling infrastructure must already be in place for the CMA450 to install correctly?

A standard 2' x 2' suspended ceiling grid is required; the plate rests on the grid and is secured by safety wire to the building structure above.

Can the CMA450 accept the 1 1/2" NPT extension column I already use with my current projector mount?

Yes, the plate provides nine threaded mounting positions that accept a 1 1/2" NPT extension column for direct compatibility.
