GFCI Extension Cords

Keep personnel safe from electric shock with these cords. The industry desgination is SJTW, so the insulation resists water.

Cords with a 90° elbow plug fit flush against a wall outlet, so they fit behind machinery or in areas where space is tight.

Use cords with an IEC C13 socket for computers, lab equipment, and office machines.

Cords with automatic GFCI reset immediately regain power after ground is established.

Cords with manual GFCI reset prevent unexpected start-up.

Cord with a power-indicating light have a light on the socket that illuminates when the cord has power.
