    I bought this then never really got the chance to use it on a trailer because certain trailers in our fleet it didn't quite fit on and then the fleet started installing that Seal Safe product so I'm back to using the War-Lok padlock only to lock the seal safe and now I use this to lock one of the hasp's on my mini storage.

    Great lock that holds up to all sorts of weather. Our nonprofit uses this lock on our disaster response trailers. The plastic cover has saved the lock from freezing over multiple times.
