EEL (Easily Engaged Lock) shorepower cordsets lock securely for a watertight seal without a special ring so it eliminates broken, cross-threaded, or missing rings. These unique cords have a built-in cord light so you can see the connection in low-light conditions. They also feature a power indicator light on both ends so you know at a glance that power is flowing throughout the cord. A secondary lock ensures the jaws cannot release and the universal connection connects to any brand, NEMA configured inlet. Watertight molded ends, corrosion resistant nickel-plated contacts and heavy duty, 6 gauge, super flexible marine grade cable all combine to make this the finest cordset on the market. 5 Year warranty, UL?« Listed.
