The STRONG SM-RBX-PRO-20-BLK is a large-format in-wall mounting box designed to house low-voltage devices, media equipment, and AV components behind flat-panel displays or within finished wall cavities. Measuring 20 x 14 inches, this enclosure provides substantial interior volume for cable management, power conditioning units, streaming devices, and other components that require a clean, concealed installation. It is intended for installation by low-voltage technicians, AV integrators, and electricians working in residential or light commercial settings.
This mounting box suits applications where a finished, recessed appearance is required for wall-mounted displays or structured wiring installations. Its large opening accommodates a wide range of behind-the-wall component configurations, making it well suited for media rooms, conference rooms, and living spaces where wire concealment and equipment accessibility are both priorities. The enclosure is sold as a single unit.
Designed as an OEM-style in-wall enclosure for low-voltage and AV mounting applications in standard wood-stud or metal-stud wall construction.
Installation is typically performed by a licensed low-voltage technician or AV integrator. Cut the wall opening to the specified rough-in dimensions before securing the box to the stud framing. Ensure all local building codes governing low-voltage in-wall wiring are followed, and verify that no electrical wiring, plumbing, or structural members are present within the planned cut zone before proceeding.
