Pollak 11-720 7-Way Round Pin Trailer Socket - Heavy-Duty Die-Cast Zinc with Solid Pins

The Pollak 11-720 7-Way Round Pin Socket is engineered for the rigors of heavy-duty commercial, industrial, and agricultural towing. Designed for the vehicle-side connection, this socket provides a robust interface for power, lighting, and auxiliary systems. Its specialized solid brass pin design ensures a stable, high-conductivity connection that can withstand the high-cycle use typical of fleet operations.

Constructed from high-strength die-cast zinc, the 11-720 offers superior impact resistance and professional-grade durability. The housing is designed to shield internal components from road salt, moisture, and debris. To ensure long-term reliability, the socket features a heavy-duty, spring-loaded cover that snaps shut with a positive-catch lid, keeping the terminals clean and dry when not in use.

Safety and reliability are at the core of the 11-720. The interior utilizes high-impact green ABS thermoplastic insulators for maximum heat resistance and dielectric strength. The solid pins provide a rock-solid mechanical fit with the trailer plug, significantly reducing the risk of voltage drop or flickering lights caused by vehicle vibration.
