GFCI Turn-Lock Extension Cords

Add GFCI protection to turn-lock connections to shield people and equipment from electric shock. These cords cut power instantly when they detect a fault. The quarter-turn lock prevents disconnection under high vibration, such as on assembly lines or heavy machinery.

Inline GFCI—The GFCI sits along the cord for easy access when you need to reset it. However, it doesn't protect the length of cord between the outlet and the GFCI.

Manual Reset—Prevent unexpected start-up by cutting electricity until you press a reset button. Choose these cords for job sites, workshops, and outdoor areas where moisture and equipment faults are common.

Power Indicator—A light indicates that power is flowing through the cord.
