Pollak 11-604 6-Way Round Trailer Connector Plug - Heavy-Duty Chrome Die-Cast Zinc

Heavy-Duty Performance for 6-Pole Systems The Pollak 11-604 6-Way Round Trailer Plug is the industry standard for trailers requiring multiple circuits, including electric brakes and auxiliary power. Engineered for the trailer-side of the connection, this plug is built to provide a secure, fail-safe link between your vehicle’s lighting system and your trailer’s equipment.

Rugged Construction for Professional Use Designed to survive where plastic plugs fail, the 11-604 features a high-strength chrome-plated zinc die-cast housing. This metallic shell offers superior protection against impact, abrasion, and the corrosive effects of road salt and moisture. Inside, the plug utilizes high-impact green ABS thermoplastic insulators and split-brass contacts that ensure a high-conductivity, "tension-fit" connection—minimizing voltage drop and preventing flickering lights.

User-Centric Engineering Pollak has integrated several features to make installation and daily use easier. A unique internal cable clamp provides robust strain relief, preventing wire chafing and protecting your electrical connections from being pulled loose. The housing is tapered with integral finger grips, allowing for easy, one-handed coupling and uncoupling even in cold weather or while wearing work gloves.
