Solid lock but mine is starting to rust. I've had this lock for about six months and it does a great job. The sliding cover over the keyhole is a nice touch. My only complaint is the rust that is developing on the shackle after only a few months. I rinse the lock down every time it comes near saltwater. I've started spraying it down with CorrosionX, between uses but then I end up with oily dirty hands. Not good for my truck's interior. August 27, 2008
Atwood Surge Brake Hitch - No This is a very nice lock and I would recommend it for anyone EXCEPT if you have an Atwood Style Surge Break Hitch. After you put the lock on, all a thief has to do is raise the release lever and the ball latch releases and the lock just falls off. July 5, 2008
No Brainer!!! Easy to use... slide cover to protect the key slot from weather, and it's HEAVY DUTY. A must have if you are going to park your boat or other trailer outside. June 10, 2008
GREAT SECURITY I have used one of these on several trailers for several years now. They are easy to use, and the added security is a warm welcome. March 16, 2008
