ProPlus adapter cable for trailer hitch socket 7/13 PIN 80cm
The 80 cm ProPlus adapter cable is a practical solution that combines the functions of an adapter and an extension cord. It allows you to effortlessly connect a modern trailer, flatbed truck, or bike rack with a 13-pin plug to an older 7-pin socket in your car . Using a flexible cable section instead of a traditional, rigid block adapter eliminates stress on the towbar socket and significantly simplifies cable management.
Key features and parameters:
- length 80 cm: the optimal cable length allows for free and safe connection of the vehicle's electrical system with the trailer, eliminating the risk of the cable being torn off during sharp turns;
- reduction of standards (13 - 7 pin): enables powering of the basic trailer lighting (turn signals, position lights, brake lights, fog light) from a modern 13-pin socket;
- solid wire construction (7 x 0.5 mm²): internal wires with a cross-section of 0.5 mm² ensure optimal current conduction and stable operation of all signal lights at a voltage of 12V;
- Durable materials: plugs and connector housings are made of hard, impact-resistant plastic, and flexible cable insulation protects it from abrasion and weather conditions.
