Chief CMA278 Extension Column Vinyl Cap, Black, 10-Piece

Give your pro display and security installations a polished, professional finish with the Chief by Legrand CMA278 Extension Column Vinyl Cap. This pipe cap is designed to slip over 1.5 in NPT extension columns to conceal rough pipe ends, improving aesthetics and reducing snag points on monitors, cameras and mounts. The pre-cut opening allows clean routing of power and network cabling, making it ideal for surveillance, monitoring and AV installations where tidy cable management matters.

Each kit includes ten black vinyl caps that resist scuffs and blend seamlessly with common mount finishes. At roughly 1.0 x 2.0 x 2.0 in, the compact cap keeps profiles low while protecting internal cabling. Built for commercial use, the CMA278 is backed by a 10-year limited warranty from Chief by Legrand—so you get dependable performance on job sites and in critical security environments.

Use these caps to complete camera poles, ceiling mounts, and display columns for a refined look and safer installations. Add the CMA278 10-pack to your next project for faster, neater deployments.
