This is a great bilt lock but it will not fit on trailers that have a rolled up metal lip on the receiver, such as Well Cargo

i own 2 trailers. first i bought one of these lock and find them to be ok. I feel that a couple of big hammer hit can remove them from the hitch, but will need work. So for the price i tought it's was ok.

Then, i bought a second one, at another store, on the other end of the city. i put it on my other trailer, put the key with the key of the others lock and leave this there for a week.

After a week i did obviouly forget to identify my key. SO i had to try it. ok key 1 in lock 1, woking cool. key 2 in lock 2, working... good i tought i was lucky. then i try key 2 in lock 1 working ? then key 1 with lock 2.... working ?!?

2 key with different tooth pattern work in booth my locks. what kind of lock is that. I finally endend removing these and i did put 2 DT security lock that do a much better job.

Bottom line. Buy something else. Anyone with a lock like this one can use hes key to open your lock.

The lock started to rust after only a couple of days outside. Overall the lock does not fit very well, it doesn't fall off, but for a 2" coupler it could fit better than it does. I honestly expected a better product than what I got.
