GFCI Extension Cords

Inline GFCI

Protect people and equipment from electric shock. These extension cords have a GFCI to cut power instantly when they detect a fault. They work even if you plug the cord into an outlet that doesn't have a GFCI.

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.

Snug-Fit Straight-Blade Connectors

Also known as hospital-grade connectors, these have an extra-tight fit to remain secure when mated under high vibration. They're marked with a green dot, so you know they're a good choice to power critical devices, such as testing and calibration equipment. While they're essential in healthcare facilities, they also power frequently moved tools and workstations so bumps and vibration won't loosen connectors.
