the lock is stout and the service was even stronger. i ordered the wrong lock and they immediately sent the correct lock out. couldn't be better people. luckily noone has tested the security of the product, but i feel confident it won't be easy to beat if they do.

These locks are awesome. This is our second one to cover our boat and box trailer. Highly recommend these, well worth the cost.

Works great and I don’t think anyone will break or cut it without making a lot of noise!

Best trailer lock by far that I’ve ever seen.

I recently purchased 3 locks for my trailers and I couldn't be more pleased with the quality, ease of installation and the Customer Service during ordering...
I puchased one of their locks about 6 months ago and just recently attempted to use it for the first time, only to find it was the wrong size. Having lost my receipt I could not verify if I had ordered the wrong lock or if the mistake was at their end. I contacted Altor, explained the situation, and asked what could be done. The rep responded that they had my original order on file, that I had ordered the correct lock, that the mistake was at their end, and they were shipping me a new lock free of charge. I find honesty and integrity to be increasingly rare commodities these days, but this company has both in spades! Thank you Altor (Thank you T.J.). Also, the locks themselves are well engineered, well made, and vastly superior to anything else that I am aware of. Thanks again.

Super robust and high quality. Best trailer hitch lock you can buy, hands down.

Great lock. Very easy to get locked up. Takes little to unlock but worth it. Can definitely tell someone will have to try hard to get. Nice way to protect my diamond c trailer.

I chose this lock because of the "Lockpicking Lawyer's" review. It is the quality expected.

I ordered what has been a fairy hard to find fit for my old school Airstream that has the curled coupler. Admittedly, the first few times I tried locking it it was hard to get the hang of it, but after a few tries I got it to lock and unlock pretty effortlessly. When locked the lock doesn’t move too much at all but it definitely does not fall off. It works as designed and I’m pretty happy with it. It has a very robust look and feel that will likely make any would be thieves move along to another target. Nice product and at a decent price. Thanks for making locks for the curled coupler. Most manufacturers don’t wanna bother. Glad you guys did!

Super impressed with the lock. Easy to install on the coupler. Well designed to protect against bad weather. Altor quickly replied to my text confirming which version to buy for my coupler. Highly recommend if the value of your trailer is a concern.

Very impressive lock. It’s the only one I could find that would fit a rolled lip receiver. A real hung of metal that will keep thieves away.

Lock fit to Bulldog style coupler is great. Will be ordering another for my other trailer.
