WORKS AS PROMISED

Works perfectly for mine and used a chain to where the ball would go in to secure it out and I used a sledge hammer to test it out because I want to make sure it works and definitely does didn’t record that part but it’s durability and material is good for the price

Tank!!

This thing is truly a tank. I just wish it came in a 2 inch size because I had to return it.

Solid

Very solid construction. It took a while to install, but after I did, it secured my trailer. I had to wiggle the hitch pin simultaneously to install the lock.

Good lock but doesn't fit on my 2 5/16" dump trailer

This is a great lock but does not work on my dump trailer. it isn't tall enough. Functions well. Good value.

Insanely heavy duty.

If you're tired of cheap trailer locks that don't last, this is the lock for you. This thing is a beast. I used to worry constantly about someone stealing my trailer because my old cheap lock provided minimal protection, but this heavy-duty lock has given me real peace of mind. It covers the entire tongue, making theft nearly impossible, and the reinforced puck lock will keep thieves at bay. Fair warning though, this lock is insanely heavy, so be careful not to drop it on your foot during installation or you'll definitely regret it. Overall, it's exactly the kind of serious security I was looking for.
