Trailer Coupler Lock 2-5/16 In, 3 Keys, Carbon Steel

Trailer hitch lock for 2-5/16 in (58.7 mm) couplers helps deter theft by securing your trailer coupler when parked or stored. Built with a carbon steel lock body and a stainless steel lock ball, it’s designed to resist prying, impact, and harsh weather exposure. The powder-coated finish supports rust and corrosion resistance for outdoor use, while the key-operated design makes locking and unlocking fast—no tools required.

Secure your trailer with a universal-fit coupler lock built for real-world towing and storage. The snug ball-style design helps block the coupler from connecting, adding a visible layer of security for campsites, driveways, marinas, and job sites. With a smooth key operation and durable materials chosen for outdoor exposure, it’s a practical upgrade for anyone who leaves a trailer unattended. Grab yours today and lock up before your next trip.
