Decorative ring for 1.9" columns

The CHIEF MANUFACTURING CMA640B decorative ring covers the ceiling opening where a fixed or inner adjustable extension column passes through a suspended tile. It provides a clean, finished appearance for projector mounting installations. The ring features a hinged design that opens for straightforward placement around the column. This accessory is intended for installers and integrators completing ceiling-mounted projection setups.

Check column type and ceiling access

Verify that the extension column in use is a CMS fixed or inner adjustable model with a 1.9" inner diameter before ordering. The hinged ring must be able to open fully around the column at the ceiling tile penetration point. Ensure there is enough clearance above the tile to manoeuvre the ring into position during installation. This part does not suit columns with different diameters or non-CMS mounting systems.

Questions about this item

Does the CMA640B decorative ring ship with mounting hardware or must I buy it separately?

The ring is a standalone accessory; mounting hardware for the CMS column is sold separately.

How do I confirm the 1.9" ID matches my CMS column before ordering the CMA640B?

Measure the outer diameter of your fixed or inner adjustable column — if it is 1.9 inches this ring will fit.
