Your 120-amp power connector on the back of a trailer, caravan, or boat shouldn't be an open invitation for rain, UV, and road dust. This black chassis-mount cover locks your Anderson or Anderson-style connector in place with a snap-fit design and a retractable access panel. PA nylon construction handles the elements. The locking tab means nobody's yanking your plug mid-drive. Towing, marine, battery charging, industrial OEM – it's built for mobile power where a loose connection is a fire waiting to happen
