The THOMAS BETTS 58 C 4 is a steel device electrical box cover designed to close and protect standard device-style electrical boxes after wiring work is complete. This cover ships with a Phillips head screw for straightforward installation. Fabricated from steel, it provides a durable finish suitable for residential and light commercial electrical applications. Electricians typically install this cover as the final step in a device box rough-in or finish-out, securing it over an outlet, switch, or blank opening to meet code requirements and protect the internal connections.
This device cover is suited for use in standard single-gang device box installations found in residential construction, renovation projects, and light commercial wiring. It is appropriate anywhere a steel cover plate is required over a device-style box, including wall outlets, toggle switches, and similar wiring devices. The included Phillips head screw means no separate hardware search is needed at the time of installation.
Designed as an OEM-style replacement or new-installation cover for standard device-style electrical boxes in residential and light commercial settings.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. Always shut off power at the breaker before working inside any electrical box. Secure the cover using the included Phillips head screw, taking care not to overtighten and crack or distort the plate. Verify the cover sits flush against the wall surface before restoring power.
