The Chief CMA152 is an in-line threaded coupler for 1.5-inch NPT extension columns. When the drop from the ceiling structure to a projector or ceiling-hung display is longer than a single column, the CMA152 threads onto the end of one column and accepts the next, producing a single continuous run. That lets installers build the exact length they need from standard column sizes instead of ordering custom pipe. The coupler is rated by Chief at 500 lbs, carries a UL listing, and measures 3.8 inches tall by 2.4 inches across, so it adds very little bulk to the column line. Its black finish matches Chief's black columns, ceiling plates and projector mounts. Because it is a structural part of the suspension, install it to the torque and safety guidance in Chief's documentation and use a ceiling attachment rated for the full load.
