Premium Turn-Lock Plugs, Sockets, and Receptacles

Also known as twist-lock devices, these connectors are built to handle tough, repetitive-use applications, and are more durable than standard turn-lock connectors. A quarter turn locks them in place to remain secure in high-vibration applications and prevent accidental disconnection.

Receptacles for outlet boxes fit standard wall plates (not included).
