Review on 🔐 Optimized for SEO: Trimax SXTC3 3.5" Span Premium Stainless Steel Coupler Lock by Marcus Hardin

I bought this lock 3 years ago to secure my boat hitch and it worked great. No corrosion and the rubber mechanical seal holds perfectly. I recently lost the end of the lock on a fishing trip so I bought it again. I don't store my boat outdoors so can't comment on how it will hold up outdoors, but this is by far the best lock I've found. Much better than the Curt and Master brands.
