Chief CMA-105 4" Ceiling Plate with 1.5" NPT Opening

The Chief CMA105 is a 4-inch ceiling plate with a 1.5-inch NPT opening that gives installers a reliable anchor point for overhead equipment. Designed for use with any Chief fixed or adjustable-length column, or with other threaded pipe that shares the same NPT size, it creates a secure connection without adding visual clutter.

Despite its compact footprint, the plate supports loads up to 500 pounds, making it a practical choice for projectors, large displays, security cameras, or other devices that need a sturdy ceiling mount. A durable black finish helps the plate blend into dark ceilings or open plenum spaces, keeping attention on the equipment, not the hardware.

Because space above a ceiling tile or in a tight soffit is often limited, the low-profile design proves helpful in classrooms, conference rooms, retail sites, and even home theaters where every inch counts. The included set screw locks the column in place, adding peace of mind when installations need to withstand daily use or occasional adjustment.

UL listing and OSHPD certification verify that the CMA105 meets stringent safety and seismic performance standards. These approvals make it suitable for commercial projects, healthcare facilities, or any environment where code compliance and long-term reliability are non-negotiable.

Installation is straightforward: secure the plate to a structural ceiling member, thread in the column, tighten the set screw, and move on to the next task. Whether you are a seasoned AV contractor or a facilities manager upgrading a single room, the CMA105 offers a quick, clean path to a professional result.
