Pollak 12-743 7-Way RV Blade to 4-Way Flat Flex Adapter – Impact-Resistant Extension

The Pollak 12-743 is a specialized "Flex" adapter designed to bridge the gap between a vehicle's 7-pole RV blade socket and a trailer's 4-way flat plug. Unlike rigid "block" adapters that can be prone to snapping or straining your vehicle's socket under tight turns, the flex design of the 12-743 provides a short length of protective harness to reduce mechanical stress and offer superior reach.

Built for the Elements Constructed by Pollak, the industry standard in heavy-duty towing, this adapter features a non-corrosive, glass-filled nylon housing. The internal wiring is shielded by a rugged split-loom conduit that protects against abrasion, moisture, and road debris. Whether you are hauling a boat, a utility trailer, or a small camper, the 12-743 ensures your tail lights, turn signals, and brake lights stay powered and protected.

Reliable Plug-and-Play Performance This adapter is the perfect tool for drivers who need a quick, no-tools-required solution for towing multiple trailer types. The 7-way end features a positive-latching fit, while the 4-way flat end provides a secure, tight connection to prevent flickering lights or power loss on the road.
