Easy to use, secure and very sturdy.
Bought my first one 15 years ago and it still works great, you can push it shut in a ratching fashion without even having the key in it. Fits trailers with 1 7/8" , 2" and 2 5/16" ball socket. Bought another for a second trailer. The design would make it difficult to pry it saw off. Much better than the u-bolt over the top design which only locks on one side and could be sawed quickly with a saws all of pryed in the non-locking side. For extra security use one of these and a lock through the latch and it isn't going anywhere.

Relatively Inexpensive Trailer Theft Protection
This Item, the Master Lock Trailer Hitch Lock, is my backup lock we utilize on our 27 ft travel trailer. The trailer lock is sturdy, and it does not appear to be easily defeated (hack saw or bolt cutters). Those 2 components were factors in my purchase. If you are on the fence about buying a trailer lock, Let me assure you it is an essential tool in the RV travel world. I would imagine that also applies to boats and other utility type trailers. I could say more...but back to this lock. After purchasing this lock and using it, I switched it out with another lock I purchased. This lock blended in with the front of the trailer, the other one I purchased was a bright red color. So, while I like it, and I still own this lock, it is a backup to the red one that screams to would be thieves "Don't bother". This is fine, works great.

Good design
Great design. Probably only honest man lock but appears sound. I would not hit it with a sledge!

Works well, decent weight to it. Won't cut through it too quickly. Fits the trailer hitch well and gives the hitch cover a place to go when a trailer is on.
