The Chief PACL2 Proximity Lever Lock Plate is a component designed to organize and securely mount audio/video equipment within specific Chief in-wall storage boxes, namely the PAC526 and PAC527L models. This accessory streamlines professional AV installations by allowing small devices to be attached and organized on the plate. It is a key part of the Chief Proximity storage system, enabling installers to pre-configure and terminate equipment before the final on-site installation, significantly increasing efficiency.

A significant feature of the PACL2 is its tool-free installation mechanism. It easily slides into the compatible in-wall boxes and locks in place using a proprietary, spring-loaded lever system, eliminating the need for extra hardware or tools during the final install phase. The plate's design includes a patented universal hole pattern that simplifies the mounting of a wide variety of small AV components. Furthermore, a unique design allows the plate to be snapped in half to create two smaller sections, offering exceptional flexibility for customizing storage space and layering components within the box at four different vertical levels.

Safety and material quality are also integral to the PACL2's design. The plate is constructed from durable metal with a black zinc-plated finish, which provides not only a clean look but also electrical grounding for enhanced safety. The robust construction allows for a maximum load capacity of up to 10 pounds (4.5 kg). It is a UL Listed component, ensuring it meets recognized safety and sustainability standards for the installation of A/V, IT, and communication technology equipment. The overall design focuses on creating a secure, organized, and reliable in-wall storage solution.
