Proximity in-wall boxes feature multi-level, multi-sectioned Lever Lock plates, making it easier to arrange components in all three dimensions of the storage space. Installers can hide power bricks behind the backplane with equipment mounted to the front. This also helps work around difficult port locations on AV equipment. The new PAC527L now includes two large tool-free Lever Lock™ plates for quick installation of AV equipment and efficient servicing of the system. Lever Lock™ plates can be mounted on four different levels to easily organize and layer components within the in-wall box. Lever Lock™ plates are compatible with Middle Atlantic Products' Forward Cable Management Solutions . Optionally also include one of the following power protection options: Two outlet Power Filter Kit PACPC1, Four outlet Power Filter and Surge Protection Kit PAC527P4-KIT, Six outlet Power Filter and Surge Protection Kit PAC527P6-KIT, Two outlet IP controlled Select Series Compact PDU with RackLink™ from Middle Atlantic Products
