Description

The CURT 56611 is a 6-foot cold-weather 7-way RV blade wiring harness designed to replace the trailer-end plug on compatible 7-way wiring systems. Its flexible thermoplastic elastomer casing is engineered to remain pliable in extreme temperatures, making it particularly well suited for trailers operated in cold climates.
