Marinco 510R 50 Amp Shore Power Sealing Collar and Threaded Ring

The Marinco 510R is a 50 amp sealing collar and threaded ring used to seal the connection between a shore power cordset and a boat's shore power inlet. The collar and threaded ring assembly compresses over the connector joint to keep out moisture, salt spray, and dirt, protecting the electrical contacts inside the connection from corrosion. It is molded in black plastic with a female connector ring configuration and rides over a stud measuring 1/2 inch in diameter, matching Marinco's 50 amp shore power connector line.

Rated for use up to 240 volts AC, the sealing collar is a simple, low-cost way to extend the service life of a shore power connection that is exposed to weather and wash-down at the dock. The ring terminal design allows the collar and threaded ring to thread securely onto the mating connector body, providing a weather-tight seal without tools. It measures 2 inches by 2 inches by 2 inches and weighs 0.15 pounds, making it easy to keep a spare aboard.
