Trailer electrical connections require secure, weather-resistant hardware, and the Phillips Industries Socket provides a 4-way split-pin configuration for commercial truck and trailer setups. Constructed with a zinc die-cast housing, it offers strong structural support for repeated coupling and uncoupling cycles. Solid brass pins promote consistent electrical conductivity, while elongated mounting holes allow flexible positioning during installation. The closed-back design helps limit exposure to moisture and road contaminants, and it can be paired with the 15-335 single-pole plug and 4 ga., 5/16-inch copper lug for proper connection. For added protection against environmental exposure, the Phillips Industries 15-400 can also be used with the P/N 15-640 socket boot to help shield the connection area.
