Not great, not horrible.August 11, 2008 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.

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
