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 CMA347 is for systems under 35 lbs (15.9 kg)

The Chief CMA-347 Projector Vibration Isolator has a unique design that soaks up vibration above the mount connection point, making it the only true vibration dampening accessory on the market today. The CMA-347 can be used with any 1-1/2" NPT extension column and includes two sets of springs for different weight mounting options.
