Chief CMA348 Large Venue Vibration Isolating Coupler, Compatible with CMS Columns for Systems Between 35-100 lbs, Black

Stop shaky images and unstable surveillance with the Chief by Legrand CMA348 Large Venue Vibration Isolating Coupler. Designed as a ceiling-mount mounting coupler for CMS columns, this patented vibration isolator significantly reduces image movement caused by HVAC, foot traffic, road vibration and doors closing—delivering steadier projector and security camera footage across large venues. The CMA348 connects two Chief CMS columns (1.5" NPT) and isolates vibrations transmitted to the lower column, so projectors and monitoring systems remain locked on target. With a higher capacity for systems weighing 35–100 lbs (15.9–45.4 kg), it supports heavier projector mounts and accessories without sacrificing performance. Finished in black and made in the US, the coupler integrates cleanly into AV, surveillance and security installations for conference centers, auditoriums and control rooms. Specify the CMA348 to improve image stability and reduce re-adjustments during live events or continuous monitoring. Learn how this isolator can streamline your next large-venue AV or security deployment and add it to your system design or order today.
