Cole Hersee 4 Pole Plug & Socket Connector w/Rubber Cap

The Cole Hersee 4 Pole Plug & Socket Connector with Rubber Cap (MPN M-115-BP) is a diecast metal electrical connector engineered for trailer, RV, and marine applications where a compact, reliable multi-circuit solution is required. Designed to handle limited functionality circuits—including taillights and brake lights—this connector delivers dependable power distribution without the complexity of larger systems, making it ideal for boat trailers, RV towing setups, and flatbed car carriers.

The connector features brass split-pin contacts precision-aligned to ensure proper engagement and minimal voltage drop across circuits. Screw terminals accept wire up to 12 AWG, accommodating standard trailer wiring gauges without adapter hardware. The replaceable interior design allows quick field service and reduces overall replacement costs—only the contact assembly needs swapping if damage occurs, not the entire connector body. The included rubber cap provides weatherproof protection when disconnected, guarding against moisture ingress and corrosion in salt-air or high-humidity environments typical of coastal and marine operations.

This 4-pole configuration is purpose-built for operators and equipment owners who need a compact, proven electrical interface without overengineering. The diecast housing provides mechanical rigidity and thermal stability, while the spring-loaded contact design resists vibration-induced disconnection during towing or rough terrain transit. Cole Hersee connectors are industry standard across marine, RV, and commercial trailer fleets, trusted where reliability directly impacts safety and operational uptime.
