Who It's For

This lock is aimed at RV, camper, and boat owners who use standard 2 5/16' or 2' round couplers and want a durable, visible theft deterrent they can fit alone in seconds. It suits families with multiple trailers because it comes with four keys and replaceable covers, making key replacement simple when needed.
