Chief - Legrand TA501 Thinstall In-wall Box Medium

Product Description

The CHIEF - LEGRAND TA501 is a medium in-wall storage box designed for use with Thinstall flat-panel wall mount systems. It mounts flush inside the wall cavity to conceal cabling, power supplies, and low-voltage components behind wall-mounted displays. The result is a clean, finished installation without exposed wiring or surface-mounted conduit. AV integrators and electricians install this box during new construction or retrofit projects where cable management and a professional appearance are required.

This in-wall box is suited for commercial and residential AV installations where wall-mounted displays require hidden cable routing. It is sized for medium applications, fitting between standard stud bays to accommodate the components and cabling typical of a flat-panel mount setup. It pairs with Thinstall series wall mount hardware to provide a complete, low-profile installation solution.

Installation Notes

Installation is typically performed by a licensed AV integrator or electrician. Power down all circuits in the work area before cutting the wall opening and routing cables. Follow local building codes and NEC guidelines for low-voltage wiring run inside wall cavities. Do not route line-voltage wiring through this box unless it is rated and permitted for that use.
