Any lock can be cut off, but this lock would make a criminal pass on by. We drop our trailer to go eat from time to time. This lock along with a pine lock gives me the confidence to do so.

Very easy to use. Trailer has not been stolen. It sits in storage at night. Seems like it would be tough to break off. Not worth the effort to win that battle. Spend the extra and buy a lock like this one.

Looks well made. But it did not fit my bulldog gooseneck coupler. Pin did not line up with holes.

When Installed, it is upside down. It has a rubber cover over the lock to protect it, however, it catches any rain/moisture you get. I live in Alaska, so this will be a problem in the winter.
