When handling daily hauling operations, maintaining stable electrical communication for light and auxiliary systems is essential for road safety. The Truck-Lite 50886 50 Series 4-Way Trailer Receptacle delivers commercial-grade reliability in a compact, low-profile footprint.

Unlike standard plastic configurations, this robust receptacle features a silver steel housing engineered to endure the physical impact, structural vibration, and heavy wear common in commercial towing environments. The 4-pin arrangement uses specialized split-type pins that provide a spring-loaded, secure contact path with matching plugs, effectively eliminating loose connections and flickering lights caused by rough roads.

Designed with fleet mechanics and owner-operators in mind, the 50886 boasts a highly practical layout. It includes an extended interior plug that safeguards the outer shell from terminal friction damage during frequent coupling. Additionally, the compact socket design utilizes exposed rear terminals to make wire routing, mapping, and installation fast and seamless. Integrated finger grips provide a positive, slip-free pull when disconnecting.
