Great Lock for Trailer Security!
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 use—just 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!

Master Lock for boat trailers or trailers
These Master locks are by far the best you can get for the price. They offer great security and a slim design. Very accountable and reliable.

Nice lock
Works well and has lasted over three years without any corrosion. A good buy in my opinion.

Great solid lock
This lock has some weight to it. It works great and feels solid. It didn’t fit on my utility trailer but that’s due to my trailer and not this lock. I gave this one to a friend and it has worked on his trailer flawlessly. Definitely worth the money. If it had actually worked on my trailer tongue I’d definitely be keeping it.

Seems like a good quality lock.
Seems to be a relatively secure tongue lock. I would not say it’s overbuilt, however it seems like it would deter the common, opportunistic thief. A well equipped thief could defeat most any lock and there’s always that someone that thinks ahead and simply chain wraps a trailer tongue and drives away.For my purpose though, I think this will be more than satisfactory.It fits tightly to my 2” trailer tongue and the lock cylinder operates very smoothly.I recommend this tongue lock considering the MasterLock name and my personal observations.

Great Master Lock!
Great lock! Makes me feel better knowing that I have this on my utility trailer. I'm sure if somebody really wanted to break this lock they could. But at least it will hopefully make somebody work to break it off. It seems heavy duty and durable, and it's very easy to install, and best of all, it doesn't break the bank. So far, I'm happy with my Purchase
