Abrasion-Resistant Turn-Lock Extension Cords
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.
Cords with a power-indicating light have a light on the socket that illuminates when the cord has power.
