Pollak 12-728 7-Way RV Blade Plug to 7-Way Heavy-Duty Die-Cast Round Pin Socket Adapter

The Pollak 12-728 is the ultimate heavy-duty adapter for drivers who need to connect a vehicle equipped with a standard 7-way RV blade socket to a trailer featuring a 7-pole commercial-style round pin connector. This harness is the rugged choice for bridging the gap between recreational towing vehicles and industrial-grade utility, flatbed, or agricultural trailers.

Maximum Durability: Die-Cast Metal Construction While other adapters rely on plastic, the 12-728 features a rugged die-cast metal socket housing. This provides maximum protection against impact, extreme heat, and heavy-duty wear. The socket is paired with a high-impact nylon RV plug, and the internal wiring is shielded by a durable split-loom conduit to prevent abrasion and weather-related damage.

Engineered for Secure Towing The die-cast socket includes a heavy-duty spring-loaded lid with a safety latching notch. This ensures that your trailer plug remains firmly seated, providing consistent electrical contact for brakes, lights, and auxiliary power—even when traveling over rough job sites or uneven terrain.
