Southwire 52151-3/4DR-UPC Steel Square Electrical Box 4x4

Product Description

The SOUTHWIRE 52151-3/4DR-UPC is a screw-on drawn steel square electrical box measuring 4 inches x 4 inches, designed to distribute power to multiple electrical devices where conductor runs split in two or more directions. Combination knockouts built into the box provide greater wiring flexibility on the job site. The box is compatible with combination Phillips/Slotted screw heads and carries UL and RoHS compliance certifications. At 0.56 pounds, it is a lightweight but durable solution for standard residential and light commercial electrical rough-in work.

This square electrical box is suited for residential and light commercial installations where a single junction point must feed multiple branch circuits or device locations. It is commonly installed in wall, ceiling, or floor applications during rough-in framing stages. Electricians rely on this style of box when conductor runs need to change direction or when multiple circuits originate from a single distribution point. The combination knockout design accommodates a range of conduit and cable connector types, reducing the need for additional fittings in the field.
