It features a reinforced zinc die-cast housing, spring-wrapped brass compression pins, and a strong cable guard (spring) to support heavy cables and prevent wire pull-out. The plug is used to terminate the trailer cable at the tractor end, providing power for lights, turn signals, and brakes. It is replaced when the original plug becomes corroded, physically damaged, or the pins wear out, ensuring reliable electrical contact and safety on the road.
