Chief PAC501B In-Wall Swing Arm Accessory Kit, 200 lb

Create a cleaner, lower-profile display installation with the Chief PAC501B In-Wall Swing Arm Accessory Kit. Designed to conceal compatible swing arm mounts inside the wall, it helps reduce visible hardware while preserving the reach and positioning flexibility of the arm. PAC501B supports PNRIW, PWRIW, and MWRIW swing arms and includes a wall enclosure, junction box, and installation hardware. The included RACO-style junction box adds electrical flexibility, while the preconfigured accessory format helps reduce time on site when paired with a pre-assembled in-wall monitor arm. With a 200 lb maximum load capacity, this kit is built for heavier commercial display applications where structural confidence matters. It is a practical choice for executive offices, hospitality environments, healthcare spaces, and premium conference rooms where the mount should disappear and the display should remain the focus. For teams standardizing on Chief hardware, PAC501B delivers a more refined finish than exposed-arm alternatives and supports a more disciplined installation standard.
