Product Overview
The Chief CMA105 is a 4-inch ceiling plate with a 1.5" NPSM fitting for anchoring CMS extension columns in conference rooms, classrooms, and commercial meeting spaces. Its compact footprint suits installations using a short extension column or locations with limited mounting space. The plate ships with a set screw for a secure column connection.
Product Description

The CMA105 is a ceiling plate designed to work with any CMS Fixed or Adjustable Extension Column, letting integrators customize a ceiling-mounted projector or display installation. Its 4" diameter makes it well suited to deployments where a short extension column will be used, or where there may not be adequate space for a larger plate. The 1.5" NPSM fitting accepts standard CMS columns and couplers, and an included set screw locks the column in place. This makes the CMA105 a practical anchor point for compact ceiling mounts in offices and meeting rooms. Pair it with a fixed CMS column to complete the drop. Browse compatible columns and additional ceiling plates in the Chief collection.
