About Extension Cords

Find the right wire gauge based on your application, power draw, and cord length.

Abrasion-Resistant Turn-Lock Extension Cords

NEMA L14-30 Plug

NEMA L14-30 Socket

Thick insulation protects the internal wires of these cords, so they can be used in high-traffic areas and over rough areas. The insulation also resists water. Give the connectors a quarter turn to lock in place; they remain secure in high-vibration applications.
