InfiniteRule 3-Pack Keyed-Alike Trailer Coupler Lock Set

The InfiniteRule Security coupler lock set protects your trailer with three keyed-alike locks that all open with the same key. The set covers a trailer coupler lock for 1-7/8", 2", and 2-5/16" balls, a latch lock, and a 2.5" receiver lock, so you can secure multiple points with one key.

Designed as a universal fit for most standard couplers — including thumb-latch, trigger-latch, yoke-latch, and sleeve-lock styles from brands like Demco, Curt, Bulldog, RAM, Fulton, and more. Machined pins and a weatherproof cap resist corrosion and tampering, and the locks are made in the USA. Offered with multiple latch lock sizes.
