Chief 24" Dual Joist Ceiling Mount

The Chief CMS394 is a 24 inch ceiling mount built for installations that span two parallel joists. It gives AV professionals and facility managers an easy way to suspend projectors, flat panels, or other equipment without hunting for a single central stud. Because the mount attaches to both joists, weight is distributed evenly and stability rises to a level that supports loads up to 400 pounds.

Chief forms the CMS394 from aluminum, a material that keeps overall weight manageable yet resists flex under heavy gear. The mount sits close to the ceiling, so it blends into conference rooms, classrooms, retail spaces, and anywhere a clean visual line is important. An internal cable path lets you route power and signal lines through the top exit port, hiding clutter and reducing snags.

After the plate is secured, a built-in lateral shift mechanism lets you nudge the column left or right for precise centering of the display. Security concerns are covered by the All-Points system, which locks hardware at key points to discourage tampering or theft. Government and enterprise buyers will appreciate that the CMS394 meets TAA requirements, and the TUV certification provides an extra layer of safety assurance.

The mount ends in a standard 1.5 inch NPT fitting, so it pairs quickly with Chief extension columns, projector mounts, or camera housings already in your inventory. Whether you are outfitting a new auditorium, updating digital signage in a retail chain, or adding a projector to a training room, this dual joist solution keeps the ceiling line neat while giving you the payload capacity and adjustability you need.
