Set Bolt Lock | Heavy-Duty Trailer Security Lock Set

Protect your trailer investment with the Set Bolt Lock — a rugged lock set engineered to secure both the hitch receiver and trailer coupler, helping deter theft whether parked or on the road.

This heavy-duty lock set features solid construction and reliable key-operated locking mechanisms designed to stand up to outdoor exposure and frequent use. The dual-lock approach means you protect both the tow vehicle’s receiver and the trailer’s coupler, reducing easy theft opportunities.

Ideal for utility trailers, goosenecks, equipment haulers, and more, this set is a smart upgrade on top of standard pins and clips — especially for long-term storage, parking lots, job sites, or unattended trailers.
