Protect your trailer and its contents with the Infinite Rule Trailer Latch Coupler Lock. This heavy-duty lock is made from high-strength steel and features a unique double-locking mechanism that makes it extremely difficult to break. This also keeps them safe from the tools of thievery (pliers?). Infinite Rule locks look good, they’re corrosion proof, and they’re the best lock design we could find. What else is there? The quality, these locks are made from stainless steel right here in our family owned factory in California using Infinite Rule machinery. By the way, these locks are keyed alike using "one-key" technology. That just means we can make keys for you forever and you can have the same key for every Infinite Rule hitch lock.

This lock is perfect for anyone who wants to add an extra layer of security to their trailer. It's made in the USA and backed by a limited one-year warranty.
