Chief PAC501B In-Wall Enclosure for Swing Arms

The Chief PAC501B is an in-wall enclosure that hides a Chief swing arm mount inside the wall, bringing a flat panel display closer to the surface and giving the room a clean, uncluttered appearance. It is built for use with Chief swing arms such as the PNRIW, PWRIW, and MWRIW, so installers can count on a precise fit and reliable support.

Large conduit knockouts on the top and bottom edges provide generous space for power, data, and control cables. Because the enclosure also accepts a metal single-gang junction box, you can locate an outlet or low-voltage plate exactly where it is needed, which simplifies cable management and keeps cords out of sight.

The housing is sized to install between three wood studs that are spaced 16 inches on center. This stud-to-stud approach means you do not have to add extra framing, and it helps maintain the wall’s structural integrity. When paired with a pre-assembled Chief in-wall swing arm, the enclosure can reduce job time because the mount drops in as a single unit.

Whether you are outfitting a home theater, upgrading conference rooms, or building a retail video wall, the PAC501B offers an easy way to achieve a flush installation without compromising access to cables and connections. Its straightforward design supports both new construction and retrofit projects, making it a practical choice for professional integrators and DIY enthusiasts who want a polished result.
