The THOMAS BETTS RSL17 is a surface-mount electrical box cover constructed from steel. It is designed to close out and protect surface-mounted electrical enclosures, providing a secure, durable finish to junction or device boxes installed on walls, ceilings, or exposed conduit runs. The steel construction delivers solid mechanical protection and meets the durability demands of commercial and industrial electrical installations. Licensed electricians and maintenance technicians are the primary installers of this cover in both new construction and retrofit applications.
This cover is suited for surface-mounted electrical box installations in residential, commercial, and light industrial environments. It is typically used where conduit or wiring enters or exits a surface-mounted enclosure and a finished, protective cover plate is required. The single-unit packaging makes it practical for individual replacement or spot repairs on existing installations.
Designed as an OEM-style replacement cover for standard surface-mounted electrical boxes used in commercial and residential wiring applications.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. Always de-energize the circuit and verify absence of voltage before removing or replacing any electrical box cover. Use appropriate fasteners for the box type and mounting surface. Inspect the box and wiring connections before securing the cover in place.
