Pollak 11-724 7-Way Round Pin Trailer Socket - Glass-Filled Nylon with Split Pins

Corrosion-Proof Reliability for Commercial Fleet Power The Pollak 11-724 7-Way Round Pin Socket is the professional’s choice for a vehicle-side connector that refuses to quit. Engineered for the most demanding towing environments, this socket replaces traditional metal housings with high-impact glass-filled nylon, making it 100% rust-proof and highly resistant to road chemicals, salt, and extreme temperature swings.

Precision Split-Pin Connectivity What sets the 11-724 apart is its split-brass pin design. Unlike solid pins, these split pins provide a spring-like tension when the trailer plug is inserted, ensuring maximum surface contact and a secure electrical connection. This "tension-fit" is critical for maintaining consistent power to trailer lights, ABS, and auxiliary systems, even when subjected to the high vibrations of long-haul trucking.

Maximum Protection & High-Capacity Performance Rated for 40 Amps of continuous duty, this socket is built to handle the heavy electrical loads of modern industrial trailers. To ensure a long service life, the terminals are factory-packed with dielectric grease, shielding the brass from oxidation and moisture. The heavy-duty, spring-loaded cover features a positive-catch lid to keep the interior clean and dry when your trailer is disconnected.
