The Chief CMA330 is an 8-inch square offset ceiling plate for 1.5-inch NPT extension columns. On a flat ceiling a standard plate sits tight against the surface, leaving nowhere for cables that run inside the column to exit. The CMA330 raises the column connection 1.75 inches off the mounting surface, creating a gap so projector power and signal cables can travel up through the column and out the top of the plate before continuing to the equipment rack or wall. The result is a clean installation with no visible cable below the ceiling. The plate fastens to the structure, the column threads in, and Chief rates the assembly at 500 lbs. Overall height is about 2.6 inches. A TAA-compliant version is available as CMA330-G.
