Building vibration from HVAC equipment, footsteps, nearby traffic and closing doors travels down a projector's column and shows up as a jittery image. The Chief CMA347 Vibration Isolating Coupler sits in line between two Chief CMS 1.5-inch NPT columns and isolates the lower column, mount and projector from much of that movement. Chief designs it for suspended systems under 35 lbs, where system weight means everything hanging below the isolator: the lower column, the projector mount and the projector itself. For reference, Chief lists typical mount weights of about 4 lbs for an RPAU and 5 lbs for an RPMAU, and CMS columns under 12 inches long average 1 lb or less. Heavier systems from 35 to 100 lbs should use the large-venue CMA348.
