Good deterrent to theft but...
Good sturdy lock and pleased with performance. It's a deterrent to trailer theft. Also recommend also using a wheel lock as well. The combo has seemingly stopped folks from trying to steal the mulch trailer. 🤞

Convenient and Secure Lock with Easy Key Access
I am amazed by how effortlessly I can secure this lock in place and unlock it with the key. It has been incredibly reliable so far, and I will definitely update if anything changes. Despite arriving slightly "opened" as seen in the picture, the excellent Amazon packaging ensured that all the parts were perfectly intact. I highly recommend this product!

Awesome product
I’ve used these for years on trailers and all have performed great with zero issues. It helps if you squirt some white lithium grease in the operable parts every once in a while to keep things functioning smoothly. Not a product defect, just the nature of storing mechanical parts outside and exposed to the weather.

Convenient and Secure Design for Peace of Mind
I love how easy it is to securely place this lock, and unlocking it with the key is a breeze. So far, it's holding up great, but I'll provide an update if anything changes. The item did arrive slightly "opened" as shown in the picture, but thanks to the excellent Amazon packaging, all the necessary parts were perfectly intact. Highly recommend!

Impressed with this reese coupler lock
Was looking for a reliable option to secure my trailer hitch and stumbled upon this Reese Coupler Lock. The heavy-duty steel construction gives me peace of mind, and the adjustable feature makes it versatile for different coupler sizes. Recently, I used it during a camping trip, and it held up well, even in rough terrain. While setting it up, someone started knocking at the back door, but I was glad to have this lock to keep my belongings safe. Definitely a handy security solution for anyone with a trailer.
