Locking Receptacles
Hubbell Wiring Device-Kellems locking receptacles provide a powerful grip on a cord in situations where it can unintentionally get detached by vibrating power tools, tripping hazards or damage to ceiling mounts. These receptacles feature a spring-loaded safety shutter that automatically ejects the plugs if not properly locked into the female device, to virtually eliminate burn-up. They have curved slots to accept matching curved blades on compatible locking plugs. These units are available in 50 and 60A current ratings on Raptor Supplies.
