Safe then sorry

Easy safe discouragement seen guys come back from fishing and they go to get truck and trailer and trailer is gone. Imagine if this could be the thing that stops the theft for so little cost.

Great way to keep thieves from unhooking your trailer from the ball.

This is made of a good quality steel that has been black powder coated for rust resistance and good looks. This is easy to lock, and comes with two keys. This fit my trailer coupler well, and it does the job. 5 Stars!

Decent device, Great price

I occasionally tow a utility trailer and needed a new lock to deter theft. This device will do that. However, it is not going to deter (or even slow down) a professional thief. It is not built for that.
It is easy to install and will prevent the coupler from being raised off the ball once locked. It adjusts easily to fit my trailer. The device is well constructed although the lock is a little cheap. I have owned similar devices in the past that were better made.
It is small and lightweight and easy to store. I can easily toss it into the toolbox I keep under my rear seat.
Overall, it should get the job done. You can’t beat the price.

Perfect lock for my needs.

I have a Tracker boat and trailer. The trailer has a small hole but long which a normal lock will not fit into, this one does. It also works on my travel trailer of which I use when travelling. Great lock.

Fits nicely

This fits nicely into the tongue lock on the trailer that I have. I like the fact that it is straight because the other one I have although it is straight, it has a curve on it and it makes it just a little more difficult to get on. I also like that the lock on this one is located where it is because it just makes it that much easier for me to Install.
