    • Works great
Size: 1 Pack
Great deterrent to any thief wanting to steal an easy target trailer. Bright red stands out to let people know it is secured with a lock. Very easy to use. Nice quality.

    • Well built and protection for my utility trailers.
Size: 1 Pack
You can spend a lot of money for a trailer hitch lock but this does a great job without breaking the bank. This is the second one of these I have purchased. The first one I have had for over 5-years and it continues to do a great job. I have one on a 2" hitch on a utility trailer and one on a dump trailers 2 /5/8" hitch. I am sure if someone really wanted to bust it off they could do so with big enough hammer, but that is going to happen to any lock if they really want to steal your trailer. ... show more

    • Trailer lock
Size: 1 Pack
I bought this to go on my travel trailer when it’s in storage. It is well made and went on easily. The lock is made so it will fit all 3 sizes of couplers.

    • Sturdy trailer hitch lock
Size: 1 Pack
This seems to be a sturdy steel lock. I slid it onto my trailer's hitch and adjusted to fit. It is adjustable for several ball sizes, which is nice. Although it might not provide absolute protection from theft, combined with other forms of protection, I think most would be thieves would look for easier pickins. ... show more

    • Easy to put on & very secure

Best lock, easy to put on. My camper sits in side driveway in winter. So this lock keeps it protected from someone driving off with it.
