The Chief CMA640B Decorative Ring is a simple finishing piece that dresses up the hole where an extension column passes through a ceiling tile or drywall. Without a trim ring, the cut edge around the column is visible from the room; this ring slips over the column and sits flush against the ceiling to hide it.
It has a 1.9-inch inside diameter sized for Chief CMS and CPA series fixed-length columns and for the inner tube of their adjustable columns, with a 3.6-inch outside diameter and a 0.2-inch profile. The black finish is chosen to match the column. Order one ring for each ceiling penetration; the column is sold separately.
