Truck-Lite 50890 – Black Small Receptacle Boot, Rear Access

Defend your trailer's electrical sockets against harsh environmental elements with the Truck-Lite 50890 Small Receptacle Boot. Molded from durable black rubber, this rear-access protective sleeve seals the back of your trailer plugs to lock out moisture, road grime, salt, and debris. Specifically sized to shield compact electrical assemblies, it fits both 2-bolt and 3-bolt flange receptacles featuring end or bottom access routing, delivering an essential barrier that prevents terminal corrosion.

The rear terminals of your trailer sockets are highly vulnerable to salt spray, rain, and road debris, which quickly cause severe corrosion and electrical failure. The Truck-Lite 50890 Black Small Receptacle Boot offers a reliable, low-cost solution designed to completely seal off these connections and keep your fleet running smoothly.

Constructed from a premium, flexible black rubber compound, this protective boot fits snugly over the back of flush-mounted trailer receptacles. Its design is optimized for rear access routing, allowing your wiring harness to feed cleanly through while maintaining a weatherproof seal around the connection points.

Engineered for smaller footprint connectors, the 50890 is highly versatile and fits both 2-bolt and 3-bolt flange trailer receptacles that utilize end or bottom wiring entry. It pairs seamlessly with popular Truck-Lite 7-way models, such as the 50868, 50869, and 50872, making it an indispensable maintenance accessory for heavy-duty commercial fleets and long-haul trailer setups.
