Chief DEC RING 2.44" ID CMS ADJ OUTER CLMN - CMA643
Product Overview
The Chief CMA643 is a decorative finishing trim ring for the outside of Chief CMS adjustable extension column pipe. It conceals the opening where the column passes through a suspended ceiling tile, giving AV integrators a clean, finished ceiling penetration. The ring is hinged for both new and retrofit installations.
Product Description
The CMA643 is a decorative finishing trim ring sized for the outside of Chief's CMS adjustable extension column pipe. It visually enhances suspended ceiling installations by covering the hole where the column passes through the ceiling tile. Because the ring is hinged, it suits both new construction and retrofit installations, fitting around a column already in place. The finish ring has an inner diameter of 2.44" (62 mm) to match the outer CMS column. The result is a tidy, professional ceiling penetration on commercial projector and display installations. Browse the full Chief collection at Creation Networks for compatible CMS columns and ceiling plates.
