When a standard extension cord with a15A-125V, 3 conductor male plug is inserted into our Pro Lock™ connector, it won't pull apart. This prevents accidental disconnects that result in an inconvenient loss of power. Simply pull down on the connector collar to disconnect extension cords.

Pro Lock™ green lighted CGM connector identifies ground continuity in the circuit. Lighted Amber Power Check plug and indicates there is power running through the cord.

ProLock™ uses high impact polycarbonate on both housing & collar on their ProLock™ connectors to guarantee hard service, extra-heavy duty use.
