The Chief CMA151 is a threaded in-line reducer that joins 1.5-inch NPT hardware to a 1-inch NPT column. It is the part to reach for when a ceiling plate or structural adapter uses Chief's standard 1.5-inch threading but the column or mount below it is 1-inch, or vice versa in a mixed-hardware retrofit. Chief lists it as compatible with its CMA and CMS ceiling accessories and with RPA Series projector mounts. The adapter is compact at 1.5 x 1.5 x 0.9 inches, is rated for 250 lbs, and carries UL listing. It has a silver finish and is TAA compliant for government and education projects. Only the adapter is included; columns, plates and mounts are sold separately. Keep the 250 lb rating in mind, as it may be lower than other components in the assembly.
