Description
The Chief Proximity® PAC527LFBP4 is an extra-large in-wall storage solution designed to simplify complex AV installations while maintaining a clean, professional finish. Featuring integrated four-receptacle power with surge filtering and Chief’s innovative Lever Lock™ mounting system, this enclosure allows installers to organize components efficiently across multiple depth levels.
Multi-level, multi-section Lever Lock™ plates make it easy to arrange AV components in all three dimensions of the enclosure. Power supplies and bulky adapters can be concealed behind the backplane while equipment remains securely mounted at the front, helping resolve challenging port locations and cable routing constraints.
The PAC527LFBP4 includes two large, tool-free Lever Lock™ plates that mount on four different depth positions, enabling fast installation, simplified servicing, and flexible system expansion. Lever Lock™ plates are compatible with Middle Atlantic Products’ Forward Cable Management Solutions, supporting clean, serviceable installations in commercial, education, and corporate AV environments.
Designed for standard 2.5" and 3.5" stud bays and UL Listed for safety, this in-wall box provides robust component support, integrated power protection, and professional-grade organization for high-performance AV systems.
