The THOMAS BETTS SSF-SR is a steel device leveler retainer designed to secure and stabilize electrical devices during installation. This small but critical accessory holds the device leveler in place, ensuring proper alignment and a flush finish at the wall plate. Electricians use this retainer during rough-in and trim-out stages of residential and commercial wiring work. Constructed from steel, it provides durable retention without flexing or failing over repeated service cycles. At 0.03 pounds, it is a lightweight component that does not add burden to the box assembly.
The SSF-SR retainer is suited for use in standard electrical box installations where a device leveler is employed to correct alignment of switches, receptacles, and similar wiring devices. It is commonly specified in both new construction and retrofit applications where precise device positioning is required. Electricians working on finish trim in residential, light commercial, and institutional settings will find this retainer a straightforward addition to their standard hardware inventory.
Designed as an OEM-style accessory retainer for use with compatible Thomas Betts device leveler systems in standard electrical box installations.
Installation of this retainer is performed by a licensed electrician. De-energize the circuit at the breaker panel and verify absence of voltage before accessing the device box. Follow applicable NEC guidelines for device installation and box fill. Avoid forcing the retainer into position, as steel components can damage device leveler housings if misaligned during seating.
