Topaz 52171-SWB 4 Square Junction Box 2.125 in Deep

Product Description

The TOPAZ 52171-SWB is a drawn 4 square electrical junction box designed for residential and commercial wiring applications. Measuring 2.125 inches deep, this box provides ample interior volume for wire connections, splices, and device installations. It features a combination of 1/2 inch and 3/4 inch side knockouts, giving electricians flexibility when routing conduit or cable. The drawn construction offers a sturdy, one-piece steel form that resists deformation during installation. Licensed electricians and electrical contractors typically install this type of box during rough-in wiring on both new construction and retrofit projects.

This junction box is suited for use in standard stud-framed wall and ceiling assemblies as well as exposed conduit runs in light commercial environments. The 4 square format is a widely recognized form factor in the electrical trade, compatible with standard 4 inch square covers, mud rings, and plaster rings sold separately. The combination side knockout pattern supports multiple conduit entry points, making it practical for installations where multiple circuits converge at a single junction point.
