Description
The Chief PAC527LFBP6 Proximity® Extra-Large In-Wall Storage Box is a clean, professional solution for organizing and protecting AV components behind the wall. Designed for modern installations, it features two large, tool-free Lever Lock™ plates that mount on four adjustable levels, allowing installers to layer and organize equipment efficiently while simplifying service access.
This in-wall box includes a dual-gang housing with isolated ground and six integrated receptacles offering non-sacrificial, multi-stage filtration and surge protection. The built-in power protection helps shield sensitive electronics from high-frequency noise and power disturbances. A paintable black flange provides a refined, low-profile finish that blends seamlessly into a wide range of environments.
Optimized for flexibility, the PAC527LFBP6 supports hiding power bricks behind the backplane while mounting equipment on the front, making it easier to work around challenging port locations. Lever Lock™ plates are compatible with Middle Atlantic Products’ Forward Cable Management Solutions, further enhancing cable organization for professional AV installs.
