Thomas Betts FSC3-TB Electrical Device Box 1 Gang Iron

Product Description

The THOMAS BETTS FSC3-TB is a single-gang rectangular electrical device box constructed from iron with a zinc-plated finish. Designed for use in standard residential and light commercial wiring installations, this box provides a secure, grounded enclosure for switches, receptacles, and other wiring devices. It measures 5.38 inches overall height, 2.75 inches overall width, and 2 inches overall depth. The zinc-plated iron body delivers solid durability in dry indoor environments. Internal ground screws are included, reducing the need for added hardware during rough-in. Electricians working under NEC requirements will find the included certifications relevant to code-compliant installations.

This device box is suited for single-gang device installations in residential and light commercial construction or retrofit projects. It is rated as non-weather-resistant and is intended for use in dry, interior locations only. With two 1-inch knockouts, it accommodates standard conduit connections for protected wiring runs. The rectangular iron body is a common choice for EMT and rigid conduit installations where a metal enclosure is required by code or project specification.
