Liftmaster K76-34771, METAL RECEPTACLE
The LiftMaster K76-34771 is a metal receptacle/outlet assembly used inside select LA500 series swing gate operator control boxes. It provides the factory receptacle mounting point and electrical outlet arrangement for the operator enclosure. When the original receptacle is damaged, corroded, loose, or missing, replacing it with the correct OEM-style assembly helps keep the control box organized and serviceable.
This is not a general-purpose accessory outlet. It must match the LA500 control box layout, wiring diagram, grounding method, and operator parts list. On outdoor gate systems, damaged receptacles are often tied to moisture intrusion, corroded conduit, loose covers, or previous field modifications, so the enclosure should be inspected during repair.
