Pollak 12-703 7-Way RV-Style Metal Trailer Connector Socket – Heavy-Duty Vehicle End

The Industry Standard for Secure Towing Connections

The Pollak 12-703 7-Way RV-Style Metal Socket is a professional-grade vehicle-end connector designed to provide a reliable electrical link between your tow vehicle and trailer. Engineered for durability, this 7-pole blade-style socket is the preferred choice for heavy trucks, SUVs, and RVs that require a rugged, long-lasting wiring solution.

Superior Durability and Weather Protection

Unlike standard plastic sockets that can crack in extreme cold or under physical stress, the 12-703 features a heavily plated metal construction for maximum corrosion and impact resistance. The spring-loaded cover includes a stainless steel spring and a moisture-resistant rubber gasket to keep the terminals clean and dry when not in use.

Engineered for Safety and Performance

Inside, the 12-703 utilizes Pollak’s unique terminal reinforcer dams. These dams prevent contact spreading and eliminate the risk of short-circuiting. The shock-resistant interior ensures consistent performance even on rough terrain, while the integrated safety latch locks the trailer plug in place to prevent accidental pull-aways during transit.
