AMPLock U-TLS2516G 2-5/16 Trailer Coupler Lock, Heavy Duty Anti-Theft with Keyed Alike Push and Lock System, Rolled Lip Fit for Travel Trailers, RVs, Campers, Boats and Cargo Trailers

Well made and simple to install.

Seems to be a really great lock. Heavy duty and well made. Fits well on our 2016 Bambi Sport 16.

Fits like a glove on our particular Airstream. Evidently there is a lot of variation between different models and years. On our trailer, the lock fits securely with minimal play and is very easy to install. It seems to be as much of a theft deterrent as one could ask for.

Third times a charm Bought two cheaper models from name brand hitch and lock manufacturers, those don’t fit an airstream This one fits like a glove and sturdy If they want it, they’ll have to work for it

The 2" fits pretty snug on the other trailer, this one flops around, but I still can NOT get it off if it is locked. I will not try to break it off. I just seem less sturdy since it moves so much. However, that may actually be better, I do not know. It has some small amount of rust on it already though. That makes me wonder a little. Time will tell. I will update over time.

I agree with the comment that seems to be a sturdy, well-built product but it does have enough vertical clearance to slip over the lip of my coupler. I can't really comment on the width as it didn't go on far enough to judge.

A battery powered grinder can remove a padlock. A large hammer can shatter many cast locks. This thing is a beast! Special security key.

Locking my in closed trailer on the tung.

This is a very good product. Arrived quickly and fits my Airstream perfectly.

This lock came highly recommended and is designed for the Airstream coupler. It's a beast and solid and although no lock is 100% secure it will make the task of a thief trying to remove it very troublesome so that they move on to another victim. The lock is not cheap but I paid good money for my RV so it's a small price to pay to protect my investment compared to the inconvenience and costs involved should it be stolen. Customer service was excellent and were very helpful recommending the correct lock for my coupler. The lock is very easy to use but I had a high spot on my coupler lip that I had to file down, no problem. The key entry is also on the bottom side of the lock so that it's protected from the weather and more difficult to pick. Highly recommended.

Excellent product. Easy to use, and wow is it tough. I'm not a theif so not goign the take an angle grinder to it to try and break it.. but this thing feels like its worth every penny....

Had to grind the lip of my '74 Airstream a 1/8" to get it to fit, but works awesome.
