The Chief CMS0709W is a telescoping extension column in Chief's CMS series that adjusts from 7 to 9 feet. It lowers a projector or flat panel mount from a ceiling plate or structural adapter, and because the length is set during installation you do not have to know the exact drop before ordering. The column is made of two nested tubes. Once the mount is at the right height, a screw through an adjustment hole and a pair of set screws lock the tubes together; Chief supplies both standard and security set screws with the matching key. Per Chief's installation guide, the adjustment holes allow 1-inch (25 mm) steps, or 2-inch (51 mm) steps when using a locking slot. Both ends carry 1-1/2-inch NPT threads. The outer tube measures 2.3 inches across, and the column is rated for a combined 500 lbs, with the lowest-rated component in the system setting the true limit. Cables can be routed inside the column. Finished in white. Ceiling plate, adapter and mount are sold separately.
