Chief CMA273 Threaded End Cap for Extension Columns

The Chief CMA273 is a threaded end cap that finishes the open end of a 1.5 inch NPT extension column, giving your mounting solution a clean, professional appearance while keeping the interior of the column free from dust and debris.

Installers rely on it wherever extension columns are visible, including conference rooms, classrooms, retail floors, and hospitality venues. By simply threading the cap into place, you remove the distraction of an exposed pipe and reinforce the sense of a purpose built installation.

The cap is made from durable material, yet it weighs only 0.6 lbs. Its compact profile, 1.4 inches high and 2.5 inches in diameter, fits easily into tight ceiling spaces and avoids interference with nearby fixtures. The black finish matches most Chief mounting hardware, so the entire assembly presents a unified look.

TAA compliance adds confidence for government, education, and corporate customers that must meet specific procurement standards. No special tools are needed; you just twist the CMA273 onto the column and the job is done.

When you want a neat ceiling line, added protection for the column interior, and a part that meets strict quality requirements, the CMA273 is the straightforward choice.
