7 WAY RECEPTICAL

This is a heavy-duty 7-way electrical socket (receptacle) used to connect the trailer electrical system to the truck. It mounts on the truck cab or trailer and accepts the standard 7-pin plug, providing power for lighting, brakes, and auxiliary functions. The socket features split brass pins for secure contact, a durable zinc die-cast housing, and a tongue-and-groove door to keep out dirt and moisture. It is commonly replaced when pins become corroded, the housing cracks, or the connector fails to maintain a reliable electrical connection.
