Chief PAC525 In-Wall Storage Box

The Chief PAC525 is an in-wall storage box that creates a clean hiding place for cables, power strips, and small AV components behind a flat-panel display. The recessed design keeps gear out of sight while allowing the screen to sit closer to the wall, giving any installation a polished, professional look.

Chief designed the PAC525 for flexibility. It drops neatly between either 3.5 inch or 2.5 inch studs and can be fitted during new construction or added to existing drywall. Break-away edges let you adjust the internal depth, and built-in knockouts accept a single-gang outlet or conduit so power and signal lines route exactly where you need them. Universal zip-tie anchors secure adapters, extenders, or extra cable slack.

The box aligns with many Chief wall mounts, including PST, PRO, PLP, MSR, and Fusion models, and it supports landscape or portrait orientation. This wide compatibility makes it a dependable accessory for living rooms, conference spaces, classrooms, digital signage, and other environments that demand a neat, reliable display setup. The steel housing is UL listed and rated to hold up to 10 pounds, giving installers confidence when they tuck away a media player, network switch, or surge protector.
