Pollak 12-729 7-Way RV Blade to 6-Way Round Adapter – Auxiliary Pin in Center

The Pollak 12-729 is a specialized towing adapter designed to connect a vehicle with a 7-pole RV blade-style socket to a trailer with a 6-pole round connector. This specific configuration features the Auxiliary/12V Pin in the center position, making it the perfect solution for trailers that require constant power for interior lights, winches, or battery charging through the center terminal.

Engineered for Durability Built to meet the demands of professional haulers, this adapter is constructed from high-impact, glass-filled nylon. The non-corrosive housing protects the internal terminals from road salt, moisture, and debris, ensuring a long service life even in harsh environments. Its full-length plug shell provides a positive, secure latch into your vehicle's 7-way socket, preventing the connection from vibrating loose during transit.

Key Features & Benefits:

• Auxiliary Center Pin: Configured with the auxiliary (hot lead) circuit in the center of the 6-way round connector.

• Rugged Construction: Glass-filled nylon shell provides superior impact resistance and won’t rust or pit.

• Plug-and-Play Simplicity: Instantly adapts your wiring without the need for cutting, splicing, or permanent vehicle modifications.

• Secure Latching: Designed with a high-retention notch to stay firmly seated in the vehicle-side socket.

• Versatile Towing: Ideal for utility trailers, horse trailers, and specialized haulers requiring center-pin power.
