🔁 Direct replacement for the discontinued Bargman #77 car end (50-77-001 / DH 597-7701). Both are standard 7-way RV blade-style vehicle-end sockets wired to RVI color standards, so the Pollak 12-707E drops in as a direct functional replacement for the Bargman #77 car-end connector.

The Pollak 12-707E is the car/vehicle end socket half of the Pollak 7-pole (7-way) RV blade-style trailer connector system. Mounted on the tow vehicle, it receives the trailer-end plug (12-706E) to deliver power for running lights, turn signals, electric brakes, and auxiliary 12V circuits. Rated 12V / 30A.

Built from non-corroding black thermoplastic, this socket eliminates the rust and seized-plug issues of metal units. The shock-resistant interior is color-coded to RVI standards, and terminal reinforcer dams keep contacts from spreading or shorting. Center pins accept up to 8-gauge wire.

A spring-loaded lid with a stainless steel spring and rubber gasket seals out moisture when not in use, while an angled drain slot sheds water and a safety latch holds the trailer plug securely in place. Perfect for RVs, boat trailers, utility, and cargo trailers.
