Pollak 11-409 4-Way Round Trailer Connector Plug - Heavy-Duty Chrome Die-Cast Zinc

The Ultimate Heavy-Duty Trailer-Side Connection The Pollak 11-409 4-Way Round Trailer Plug is a professional-grade electrical connector designed for those who demand more than standard plastic hardware. Built for the trailer-side of your electrical system, this plug is ideal for utility trailers, marine applications, and light-duty commercial towing where a rugged, reliable connection is non-negotiable.

Unrivaled Durability & Corrosion Resistance Encased in a premium chrome-plated zinc die-cast housing, the 11-409 is engineered to survive harsh road environments and salt-heavy marine conditions. Inside, it features high-impact green ABS thermoplastic insulators and split-brass contacts. These contacts ensure maximum electrical conductivity and a secure "tension-fit" that resists vibration and accidental disconnection while you're on the move.

Simplified Installation & Use Pollak has designed this plug with the user in mind. It features a unique internal cable clamp that provides superior cable support, preventing wire chafing and strain. The exterior is tapered with integral finger grips, making it easy to plug and unplug even while wearing heavy gloves. With its polarized design, you can trust that your wiring will align perfectly every time, protecting your lighting system from shorts and cross-connections.
