Known for their keyed-alike hitch lock sets, TOWWORKS delivers products engineered for Class III and IV hitches, featuring extra-long spans and double safety mechanisms to keep your trailers and equipment firmly in place during travel.

Why Choose TOWWORKS for Your Towing Needs

TOWWORKS focuses on practical, heavy-duty solutions that prioritize security and convenience. Their hitch locks are designed with universal compatibility in mind, fitting standard 2-inch, 2.5-inch, and even 3-inch receivers, as well as adjustable channel mounts.

This eliminates the hassle of carrying multiple keys, making setup and release quick and efficient.

Built with robust 5/8-inch pins, TOWWORKS locks provide superior strength against prying and cutting attempts.
