CHIEF MANUFACTURING CMA640B decorative ring 1.9" ID projector accessory

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.
