The ARLINGTON INDUSTRIES FLBR5420AB is a recessed in-wall box designed for retrofit installations where a finished, flush-mounted appearance is required. Built to accept both standard electrical connections and low-voltage wiring, this box suits applications where cables, connectors, or media plates need to be neatly housed behind the wall surface. Electricians and low-voltage installers use this box when a clean wall finish is the priority and surface-mounted hardware is not acceptable. The single-unit packaging makes it straightforward to order by the piece for targeted installs or small jobs.
This recessed box is suited for residential and light commercial interior wall installations. It is commonly used behind wall-mounted televisions, home theater equipment, structured wiring panels, and similar low-voltage runs where cable management and a finished look are required. The retrofit design allows installation into existing drywall without demolition or major modification to the wall cavity.
Designed as an OEM-style recessed in-wall box for retrofit low-voltage and electrical applications in standard drywall wall assemblies.
Installation is typically performed by a licensed electrician or qualified low-voltage technician. De-energize all circuits at the breaker panel before beginning work and verify with a non-contact voltage tester before handling any wiring. Follow all applicable NEC requirements for box fill, conductor support, and low-voltage separation. Cut the wall opening carefully to match the box dimensions to ensure a secure, flush fit against the drywall.
