Purpose and Fit

The Chief CMA643 decorative ring finishes the ceiling opening where a CMS adjustable column passes through a suspended tile. It is intended for installers and AV professionals who want a clean, professional appearance around the column penetration.

Critical Dimension

The ring has an inner diameter of 62 mm, matching the outer pipe of the CMS extension column. This single measurement determines whether the trim will seat correctly on your specific column assembly.

Who Should Buy and Who Should Not

Suited for new builds or retrofit projects where the column is already in place, thanks to the hinged design that opens for installation without disassembly. Not suited for installations using a different column diameter or for ceilings that cannot accommodate a surface-mounted trim ring.

Questions about this item

How does the 62 mm inner diameter fit around the CMS column in a real installation?

The ring's 2.44 inch inner diameter matches the outer pipe of the CMS adjustable extension column so it covers the ceiling-tile cut-out cleanly.

What mounting standard does the hinged ring use to attach to the ceiling?

It simply clamps around the column itself; no separate ceiling bracket or thread standard is involved.

What clearance does the 62 mm ring need above the ceiling tile to hinge open?

The ring hinges at its joint so it can swing open around the column without requiring extra plenum height.
