Chief - Legrand PAC527LF Large In-wall Box 14.25x22

Product Description

The CHIEF - LEGRAND PAC527LF is a large in-wall enclosure box designed to house low-voltage cabling, back boxes, and related components behind flat-panel displays and wall-mounted equipment. Measuring 14.25 by 22 inches, it provides a clean, code-compliant pathway for managing wires within the wall cavity. The box includes a flange for secure mounting against drywall surfaces, keeping installations neat and professional. Licensed electricians, AV integrators, and low-voltage installers typically deploy this enclosure during new construction or retrofit projects where in-wall wire management is required.

The PAC527LF is suited for residential and light commercial applications where low-voltage cabling — such as HDMI, coaxial, speaker wire, and data cable — needs to be routed inside the wall behind mounted displays or projector screens. It works within framed wall cavities and is sized to accommodate a range of bracket back boxes and accessory components. The flanged design allows it to sit flush against the finished wall surface for a clean final appearance.

Installation Notes

Installation is typically performed by a licensed low-voltage technician or electrician in accordance with local building codes and NEC Article 725 for low-voltage wiring. Power down and de-energize any adjacent circuits before cutting into the wall cavity. Verify stud spacing and wall depth before marking the cutout to ensure the enclosure fits without obstruction. Do not route line-voltage conductors through a low-voltage enclosure.
