Thomas Betts 52151 Gb Steel Square Junction Box 2 Gang

Product Description

The THOMAS BETTS 52151 GB is a steel, square electrical junction box designed for residential and commercial wiring applications. Measuring 4 inches high by 4 inches wide by 1.5 inches deep, this 2-gang box provides ample interior volume for wire splices, device mounting, and conduit terminations. It features 14 knockouts sized at 1/2 inch and 3/4 inch to accommodate standard trade-size conduit and fittings. Constructed from steel with screw mounting, it is built for durable, code-compliant installations in dry, non-weather-resistant locations. Licensed electricians and experienced tradespeople are the primary installers for this type of enclosure.

This junction box suits standard residential and light commercial electrical rough-in work. It is appropriate for new construction and retrofit installations where a 2-gang steel enclosure is required. The dual-gang configuration supports side-by-side device mounting or provides space for organized wire management within a single box. Its non-weather-resistant rating limits use to interior or protected locations only. The 14 available knockouts give installers flexibility in conduit entry routing from multiple sides of the box.
