Chief XL VIBRATION ISOLATOR COUPLER - CMA348W

Product Overview

The Chief CMA348W is an XL projector mount vibration isolator coupler that reduces on-screen image movement caused by everyday building vibration. It installs between two Chief CMS extension columns and damps vibration transmitted to the lower column and projector. The higher-capacity design accommodates heavier projector systems weighing 35 to 100 lbs (15.9 to 45.4 kg). It is a practical fix for venues where HVAC cycling, foot traffic, or nearby roadways cause a visibly unstable projected image.

Product Description

The CMA Large Venue Vibration Isolating Coupler addresses one of the most persistent complaints in ceiling-suspended projection: image shake. Common building vibrations—HVAC equipment, foot traffic, road traffic, and doors shutting—travel through the ceiling structure and into the projector, causing the image to jitter. The CMA348W's patented design connects two Chief CMS columns (1.5-inch NPT) and limits the vibration that reaches the lower column, stabilizing the projected image. This XL version carries a higher weight capacity than the standard coupler, supporting complete systems between 35 and 100 lbs. System weight includes everything below the isolator: the lower column, the projector mount, and the projector itself. The white finish matches white CMS columns and white ceiling environments. Installed inline as part of the column run, it requires no change to the projector mount itself. For lighter systems, compare the standard CMA348, or browse compatible columns and mounts in the Chief collection.
