Chief DEC RING 1.9" ID CMS ADJ INSIDE CLMN - CMA640
Product Overview
The Chief CMA640 is a decorative finishing ring (1.9" ID) that conceals the opening where an extension column passes through a suspended ceiling tile. It gives AV integrators a clean, finished look on ceiling-mounted projector and display column installations. The ring is hinged to open for easy installation around an existing column.
Product Description
This decorative finishing ring visually enhances suspended ceiling installations by covering the hole where the extension column passes through the ceiling tile. Because the ring is hinged to open, installers can fit it around a column that is already in place without disassembling the mount. It is compatible with fixed CMS extension columns and fixed CPA columns, making it a versatile finishing accessory across Chief ceiling mounting systems. The result is a tidy, professional ceiling penetration in commercial and institutional spaces. Browse the full Chief collection at Creation Networks for compatible ceiling columns and plates.
