Ceiling Plate for Projector Mounts

The Chief Manufacturing CMA-115 is a flat ceiling plate designed to anchor a projector mount to a drop ceiling. It accepts standard 1-1/2 inch NPT pipe threaded on both ends, allowing installers to choose the drop length required by the room height. The plate also connects directly to any Chief CMS fixed or adjustable extension column. Its compact 6 inch diameter suits installations where space above the tile is limited.

Weight Capacity of 500 lbs

The single specification that determines suitability is the rated load limit of 500 lbs (226.8 kg). This capacity covers virtually all commercial and residential projectors, so the plate will not be the limiting factor in a typical installation. The UL listing confirms the rating has been independently verified for safety. Installers must still ensure the building structure and fasteners can support the same load.

Suited for Low-Profile Drop-Ceiling Installs

This plate suits installers who need a minimal footprint above a suspended ceiling tile and who plan to use NPT pipe or a Chief CMS column for the vertical drop. It is not for installers who require a larger mounting surface to span multiple joists or who need an integrated junction box for electrical connections. Buyers without access to 1-1/2 inch NPT pipe or compatible Chief columns should look at other mounting systems.

Questions about this item

What does the 500 lbs weight capacity mean for my projector setup?

How does the NPT 1-1/2" pipe interface work with extension columns?

The plate accepts standard NPT 1-1/2" pipe threaded on both ends and also fits any Chief CMS Fixed or Adjustable Extension Column for custom drop lengths.

What ceiling space is needed to mount the 6-inch flat plate?

The flat 6-inch diameter plate is designed for tight plenum spaces where a larger canopy will not fit, and it mounts directly to the structural ceiling above a drop tile.
