Marinco 103RN Weatherproof Cover with Threaded Sealing Ring for 20A/30A Female Connectors, Black

The Marinco 103RN is a weatherproof cover designed to protect 20 or 30 amp female marine electrical connectors from moisture, salt spray, and debris when the connector is not in use or is mated to a male plug. Built from heavy-duty vinyl in black, the cover uses a threaded sealing ring construction that provides a superior seal when the female connector is fitted with a 20 or 30 amp male plug in combination with a 102N boot and a 110R sealing collar. On its own, the 103RN is intended for 20A/30A female connectors such as the Marinco 305CRCN and 205CRCN and should not be used on a male plug -- the 103RN boot will not fit a 20 or 30 amp male connector.

This cover is a common accessory for boats using shore power inlets and cord connectors, helping prevent corrosion and electrical faults caused by water intrusion around the connector body. It is rated for full exterior boat coverage and offers waterproof, genuine ultraviolet light protection to resist cracking and fading from prolonged sun exposure. The vinyl construction is flexible enough to seat securely over the connector while remaining durable in a marine environment.
