The Chief CMA640W is a slim decorative ring that finishes off a projector or display ceiling column. It is sized with a 1.9-inch inside diameter, so it slides over a Chief CMS or CPA fixed-length extension column, or over the smaller inner tube of a CMS/CPA adjustable column, and sits flat against the ceiling plate or mount it threads into. The result is a clean transition that covers exposed pipe threads and the edge of the fitting. At 3.6 inches across and only 0.2 inch thick, the ring is unobtrusive, and its white finish suits white columns, white mounts and light ceilings. It is a cosmetic accessory only: it carries no load and does not change how the column is installed. Chief catalogs this part as a decorative ring; the ITS description refers to it as a shield ring.
