Southwire G1939 Square Exposed Work Cover Duplex

Product Description

The SOUTHWIRE G1939 is a 4-inch square, half-inch raised industrial surface cover designed to mount two duplex receptacles directly onto 4-inch square electrical boxes in exposed or industrial environments. The raised profile accommodates standard duplex devices while keeping the installation flush against the box. This cover is sold in a 50-pack, making it well suited for large commercial or industrial electrical projects. Licensed electricians and journeymen installers use this cover when wiring exposed-work applications where conduit and surface-mounted boxes are the standard method of wiring.

This cover is intended for industrial and commercial settings where 4-inch square steel boxes are mounted to walls, columns, or structural surfaces without drywall or other finish materials. It is a go-to solution on construction sites, warehouses, manufacturing floors, and utility spaces where exposed conduit wiring methods are required. The design allows duplex receptacle devices to be attached to the steel cover before the cover is fastened to the box, simplifying staging and installation workflow.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify absence of voltage before working on any box or device. Attach duplex receptacle devices to the cover first, then secure the cover to the 4-inch square box using appropriate box screws. Inspect the mounting surface to confirm the box is securely fastened before completing the installation.
