### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    No way someone is going to steel my trailer with this on it.
  

*by G***N on Reviewed in the United States on April 22, 2024*

Really solid and well made. No way to get it off so don't lose the two keys. I feel safe leaving my trailer anywhere now. It is also easy to install and lock. Yes, you can't see the key hole but I have never had trouble getting the key to slip in the key hole and locking or unlocking it.

    THIS THING IS STOUT!!
  

*by N***H on Reviewed in the United States on August 21, 2023*

I’m using this on a trailer loaded up with our family’s dirtbikes.  When we need to park the trailer it gets a lot of locks, and this looked like a good way to help keep the trailer right where I wanted it.No disappointment!  It is a rhinoceros of a lock!  Fit perfectly onto the lip of the 2” coupler, locking pin slides up into the coupler, key comes out smoothly.  I like that the key is very non-traditional in shape and style, and that it turns the opposite direction to what you’d expect.  Extra hiccups for the crooks out there, and honestly just looking at the thing is probably going to make most trash keep going for an easier grab.  I realize any security can be defeated with time and determination, but this is a massive chunk of steel that won’t be undone quickly.If there’s a negative to it, it’s that the lock is really heavy, although that’s how physics works when you make something big from dense substances.  You won’t forget this in your pocket.  You may not have a pocket if you put it in there.  I would buy this again in an instant but can’t see why I would ever need to.

Great coupler lock.  Fits tight and securely.  Better built than others I have looked at. Made in the USA!
