Proven Industries Model 2516-B Trailer Lock, Fits 2 5/16-Inch Bulldog or Ram Trailer Couplers, Made in The USA, (Black)

It was very easy to put on the hitch.It encompasses the whole hitch and the lock fits snug so it would be hard to cut it off. The lock has a special key that I would say is hard to pic. It’s thick steel and is powder coated I guess so it does not rust. Very satisfied with the purchase even though it was pricey but worth it.

The price made me concerned, but this is an excellent, well designed product and it even looks cool. Leaving my travel trailer with this in place makes me feel it is secure and that it would take more than an angle grinder to remove it.

Material is strong, fit my Ram hitch perfectly! No ones getting that thing off.

This thing is a beast. I think it has to be the most secure way to lock, available. I’m sure everything is detestable, but I feel this is as good as it gets. I guess the idea is to convince them to find something easier than your trailer

This product does exactly what it is supposed to do. Very happy with the quality as well.

Bought this lock for my new trailer. I have been keeping the trailer in the garage but sense receiving the product I can confidently leave it under a carport. It is well made and the designs looks like it would rehire people for loop trying to open it.

The media could not be loaded. Was excited to get this lock. Heard a lot about the company. Disappointed on the amount of movement the lock had and the fact I can’t put my chains inside the lock. Other than those two concerns the lock will do its job.

It’s very heavy duty. Definitely would discourage a theft. The weak link might be the lock itself. Best trailer lock on the market.

Great design and will protect your trailer. Worth the price for piece of mind.
