Grote 87220 Ultra-Pin Receptacle – Split Pin, 7-Way Trailer Connector, Three-Hole Mount, Receptacle Only

Heavy-Duty Electrical Connectivity for the Road Ahead™

The Grote 87220 Ultra-Pin Receptacle is a high-performance electrical interface designed for professional-grade power delivery in tractor-trailer applications. This 7-way receptacle features a split pin design, engineered to provide a secure and consistent electrical connection by maximizing contact surface area. Built to withstand the rigors of heavy-duty hauling, it serves as a reliable replacement or upgrade for your trailer's primary power interface.

Designed for Maximum Durability and Corrosion Resistance

Constructed from high-impact, non-corrosive materials, the 87220 is built to outlast the elements. It features a robust housing that resists road salt, chemicals, and UV damage. To ensure long-term electrical integrity, the receptacle is designed with a spring-loaded door and a high-quality gasket that seals the interior terminals from moisture and debris when not in use. This "receptacle only" configuration is perfect for fleets looking to maintain or repair existing Ultra-Pin systems without replacing the entire housing.

Secure and Stable Three-Hole Mounting

The 87220 is engineered for stability, featuring a three-hole mount pattern that ensures a vibration-resistant installation on the trailer front or nose box. The split pin terminals are crafted from high-conductivity brass to minimize voltage drop and provide superior current capacity for lighting and auxiliary systems. Whether you are outfitting a new trailer or performing fleet maintenance, the Grote Ultra-Pin system delivers the reliability required for modern transportation.
