Decorative Ring, 1.9 Inch ID, CMS/CPA Fixed/Inner Adjustable Column
Decorative ceiling trim ring with a 1.9" ID and hinged design for CMS and CPA series columns
The Chief CMA640 is a decorative finishing trim ring designed to provide a clean aesthetic for suspended ceiling installations. This accessory visually enhances the installation by covering the hole where a CMS or CPA series column passes through the ceiling tile. It features a 1.9" (49mm) inner diameter (ID) and is constructed with a hinged design. This hinge allows for easier installation in both new construction and retrofit scenarios by allowing the ring to open around the column. This silver-finished ring is specifically intended for use with the CMS Outer Adjustable Column series and is compatible with both fixed CMS extension columns and fixed CPA columns.
