Product Details
11-Foot Arctic Blue Cold-Weather 7-Way Trailer Cord with Junction Box
Part Number: J-JB-11FT
Heavy-duty 11-foot Arctic Blue cold-weather rated 7-way trailer cord with molded RV-style plug and weather-sealed junction box. Designed for utility trailers, cargo trailers, snowmobile trailers, equipment haulers, and commercial applications exposed to extreme winter conditions.
Arctic-grade jacket remains flexible to –40°C (–40°F) while heavy-gauge copper wiring supports brake, charge, and lighting circuits.
R&P Knowledge Hub
Cold-weather trailer cords must remain flexible in freezing temperatures. Standard PVC jackets stiffen and crack under repeated flexing in winter conditions. Arctic-rated thermoplastic elastomer jackets maintain flexibility and reduce wire fatigue.
Junction box systems allow cleaner installations by eliminating butt connectors and providing labeled studs for secure wiring.
