Compact Ceiling Plate for Tight Spaces
The Chief Manufacturing CMA105 is a 4-inch black ceiling plate designed for projector mounts where clearance is limited. It connects directly to any CMS fixed or adjustable extension column. The plate supports loads up to 500 lbs (226.8 kg). Installers working in confined plenum areas or low ceilings will find the small footprint practical.
Sustained Load Performance
The plate carries a static weight rating of 500 lbs and holds OSHPD approval plus a UL listing for structural safety. These certifications confirm the steel construction maintains integrity under continuous heavy load without deformation. The 0.70-inch thickness provides rigidity during long-term installations. Vibration from projector fans does not loosen the column connection when the set screw is properly tightened.
Installation Notes
Mounting requires anchoring the 4.00-inch square base to a structural ceiling member using appropriate hardware for the substrate. The included set screw secures the extension column to the plate once positioned. A common issue occurs when installers use drywall anchors instead of lag bolts into joists, risking failure under the rated capacity. The compact size leaves little room for error in hole alignment.

Questions about this item
Does the 0.70-inch height of the CMA105 plate leave enough clearance for heat to rise from a projector running all day?
The plate is 0.70 inches tall and 4.00 inches square, so it adds minimal profile; heat dissipation depends on the projector's own vents and the column length you choose.
Which extension column must I already own to mount this CMA105 ceiling plate?
It requires any Chief CMS fixed or adjustable extension column; the plate includes a set screw to lock onto that column.
Will the UL-listed CMA105 support the same 500 lb capacity if I attach it to an older CMS column I already have?
Yes, the plate is rated for 500 lbs (226.8 kg) and is designed to work with any CMS column, so the combined system keeps that capacity.
