OneMonroe's Integro manufactures a line of industry standard power cords, extensions and distribution systems. All connections are based on the NEMA 5-15 (U-Ground) specification. As with our other lines of power equipment, our industry standard power cords provide superior safety and reliability. All U-Ground connectors are molded in synthetic rubber for a permanently sealed connection (rather than assembled), and serve as high quality plugs and receptacles that are ideal for operation in extreme marine conditions.
