    Description
    This 25 ft undermount extension cord is designed to extend power connections for dock lighting installations using SF and DM model lights. Built with 18 AWG, 2-conductor marine-grade cable, it delivers reliable performance in harsh waterfront environments. The IP68-rated waterproof quick-connect connectors provide secure, sealed connections and are rated for submersion up to 50 feet. A conversion kit is included to ensure compatibility with older model lights, making this extension a versatile solution for new and existing dock lighting systems.
