I have looked at a lot of trailer locks and this was the best for the money.

So far, I'm impressed with the lock. It fit the tongue exactly and it's easy to get on and off. It's definitely heavy duty.

I bought this to use on my enclosed trailer while it is sitting on the different job sites. Peace of mind knowing my trailer is secure

This lock is heavy and durable. I am using it on my Pequea car hauler 2-5/16" coupler. I am able to get the safety chains inside and with a couple of twists shorten them so they can't be used to drag the trailer away. As far as I can tell this lock does everything the more expensive versions do and is just as sturdy. I would recommend this for any 2" and 2-5/16" straight tongue coupler that it is designed to fit. It's important to select the lock that is made to fit your coupler style. It is easy to put on and take off. Yes, it is heavy but not too cumbersome once you get the hang of the installation. This model does not cover the the receiver latch lever. It does butt up against it so that it cannot be released manually. A coupler latch lock will fit and is recommended in addition to this coupler lock. If you need additional security I would pair this with a wheel clamp or chain and lock through the wheels (on a tandem trailer) or even chain your trailer to a large tree through a stake pocket or other solid point. As with any lock, it secures against opportunists, however anyone with sufficient time and appropriate tools can get into anything.

I needed a security system for my 2-5/16 hitch, that had an unusual profile, with the flange high on the hitch, not along its lower edge as is most common. VEVOR was good enough to post dimensions in its prod desc. Looked to me like with modifications it could work. See pics--I had to cut out a 3/4 inch section (shown as a red rectangle) of the "ball's" shank portion of the lock that fit inside the hitch in order to raise everything up so that the larger part of the inside diameter of the mechanism was high enough to clear the hitch flange. See how the tabs match up perfectly so the lock will go through like it should. Worked perfect, other than the welding heat being hard on the powder coating, but who cares. No other changes were required. The product itself is all steel and very heavy except for the lock, and will take a serious effort to remove it without the key. In that regard this design is vastly superior to any other style I could find anywhere. Everything else available looked easily cut with a portable die grinder and cutoff wheel or bolt cutters. Not this one. You would be cutting for a very long time, or beating on it forever. I guess the lock itself is good--can't say. Looks hard to pick, first because it is facing down so you would be working over your head while laying on your back, and second with unusual tumblers and a key with different notches on each side of the key with a rib down the middle. You would have to fit two picks inside at the same time.

This trailer lock fits the trailer hitch and appears to be providing much better protection than my previous lock
