Pollak 12-725 6-Way Round Pin Plug to 7-Way RV Blade Socket Adapter Harness

The Pollak 12-725 is the professional-grade solution for vehicle owners with a standard 6-pole round pin socket who need to tow trailers equipped with a 7-pole RV-style blade plug. This heavy-duty harness adapter eliminates the need for permanent rewiring, allowing you to switch between utility trailers and modern campers or horse trailers with ease.

Rugged Engineering for the Road Constructed with a non-corrosive, glass-filled nylon shell, this adapter is built to survive the toughest environments. Unlike standard plastic adapters, the Pollak 12-725 resists impact, moisture, and road chemicals. The internal wiring is protected by a durable split-loom conduit, ensuring that your electrical signals stay shielded from abrasion and debris.

Secure and Weatherproof Design The 7-way RV blade socket features a high-tension spring-loaded lid that keeps the connection secure while driving and seals out dust and water when not in use. On the vehicle side, the 6-way round plug provides a positive, latching fit for consistent electrical contact across all circuits.
