Best trailer lock ever.

The TL10 is the best trailer lock I’ve ever had. Easy to use, easy to care for, and ease of mind. It has more than paid for itself in security for the Great Dane and wabash trailers I pull. Doesn’t work on our utility reefers though, the latch on them is curved too much to fit.
