EZ Connector's patented EZ Recreational 7-Pin Heavy Duty Plug (EZR7) is the first plug/socket combination of its kind on the market, and is ideal for a variety of recreational, non-commercial and commercial applications, including boating, farming, RV, trucking and other activities. Designed with ease-of-use and reliability in mind, the EZR7 improves reliability of the vehicle/trailer connection. Compared to the electrical connections within today's traditional pin/socket plugs, the EZR7 uses spring-loaded face-to-face contacts, ensuring both faultless and safe connections. And, because the EZR7 is double O-ring sealed whether in use or not, it is always clean, waterproof and corrosion free. In addition, because it is magnetically held together, in the event of accidental disconnection, there is no damage to the plug, socket or cable.
