Thomas Betts 72151-1/23/4E Square Outlet Box 2 Gang

Product Description

The THOMAS BETTS 72151-1/23/4E is a steel, square electrical outlet box designed for standard commercial and residential wiring installations. Built from pre-galvanized steel, it provides a durable, corrosion-resistant enclosure for device mounting and wire management. The box measures 4-11/16 inches in height, 4-11/16 inches in width, and 1-1/2 inches in depth, accommodating 2-gang device configurations. It includes 16 knockouts sized for 1/2-inch and 3/4-inch trade-size conduit entries. Licensed electricians install this box during rough-in framing or masonry work as part of branch circuit wiring systems.

This outlet box is suited for use in both new construction and renovation projects where a flush-mount, square steel enclosure is required. The 2-gang configuration supports dual-device installations such as duplex receptacles, switches, or combination devices. The pre-galvanized finish is appropriate for dry and damp interior locations. It is not rated for outdoor or weather-exposed applications. Electricians working on commercial tenant build-outs, light industrial spaces, and residential framing commonly specify this box type for conduit-fed wiring systems.
