The SOUTHWIRE G1939-UPC is a 4-inch square, 4-outlet surface cover designed to close and finish a standard 4-inch square junction box. The cover provides secure device mounting in surface-mount industrial and commercial electrical installations. Its crushed corner design allows the use of standard box cover screws, making it compatible with common installation hardware already on the job. This cover is UL listed and RoHS compliant, meeting requirements for both safety and restricted hazardous substance standards. Electricians and electrical contractors install this cover during rough-in and finish work on commercial and industrial wiring systems.
This cover is suited for industrial and commercial surface-mount applications where a 4-inch square junction box requires a finished, functional cover. The 4-outlet configuration supports device attachment directly to the cover face, making it practical for receptacle, switch, or device mounting in surface conduit wiring systems. It is commonly used in warehouses, manufacturing facilities, and commercial buildouts where surface-mount wiring methods are standard practice.
Designed as an OEM-style replacement and standard fitting for 4-inch square junction boxes used in surface-mount industrial and commercial electrical installations.
Installation is performed by a licensed electrician following applicable NEC requirements. De-energize the circuit and verify the absence of voltage before opening the junction box or attaching the cover. Secure the cover using standard box cover screws through the crushed corner mounting points. Ensure all conductors are properly terminated and contained within the box before fastening the cover in place.
