Product Overview
The Chief CMA330-G is an offset fixed ceiling plate that routes projector or display cables through the extension column and out the top of the plate for clean cable management. It attaches to a 1.5" NPT threaded extension column and is intended for flat-ceiling commercial AV installations. The plate is TAA-compliant for U.S. government projects.
Product Description

The CMA330-G allows projector cables to be routed through the extension column and out the top of the ceiling plate, keeping cabling concealed in a ceiling-mounted installation. It includes an 8" (203 mm) square ceiling plate with a 1.75" (44 mm) high offset, and that offset provides a cable exit when mounting to a flat ceiling surface. The plate attaches to a 1.5" NPT threaded extension column, the common interface across Chief's ceiling mounting system, with an overall height of 2.63" (67 mm). As a TAA-compliant component, it meets the procurement requirements of U.S. government and public-sector projects. It is a practical base for projector and display drops in auditoriums, conference rooms, and commercial meeting spaces.
