The CMA Large Venue Vibration Isolating Coupler reduces image movement caused by common building vibrations like HVAC, foot traffic, road traffic and doors shutting. The patented design works as a projector mount vibration isolator by connecting two Chief CMS columns (1.5" NPT) and limiting vibrations that are transmitted to the lower column. The higher weight capacity accommodates systems weighing 35-100 lbs (15.9 - 45.4 kg).
