I use this on both a 1 7/8 inch and a 2-inch kayak trailer that I keep in a storage unit. It's nice to have this extra measure of security.

The description for the coupler lock did not state what type of metal it was constructed of. It appears to be brass. It is heavy duty, but it could be cut off much easier than if it were made of steel. I have had it for 3 years now and the paint is starting to peel off. For the price, it has done the job, but I will purchase a steel coupler lock when I replace it.

I like the value for money, added peace of mind knowing my sxs trailer is secure and not easily stolen while I’m away. The build quality is solid, I like the look and the ease of installation. The key functions easy for installation and removal.

I bought the Master Lock Universal Trailer Coupler Lock, and it's been a great addition to my RV setup. It fits perfectly on my 2-inch coupler. It’s solid, durable, and provides that extra layer of security when I’m parked at campgrounds or when my trailer’s stored. The lock is easy to usejust slide it on, lock it in place, and I feel much more confident leaving the trailer behind. It’s made of heavy-duty materials, so I’m not worried about it rusting or breaking. Overall, this Master Lock is a great value for the price and provides peace of mind that my trailer is secure. I highly recommend it to anyone with a trailer or RV!

Seem to work well and easy to see.. Do not know how durable. I wonder if a hammer might break it. I am using this on a 2-5/16 hitch.
