Model 400XL

It only fits one of my doors

This puck lock only fits my side door because the hasp is bent out. The two that are on the back. The hasp are bent in and there’s no way that I can get the puck locks on even if when drilled out one hole it still don’t fit because of the way the hasp are bent in towards the trailer door so it doesn’t leave any room because the one on the side door the hasp is bent out, and it was easy to get on

Great Locks

This is my second time buying these, I recently purchased a new trailer and with the good job they have done on trailer one there was no question which lock system I was getting for the new trailer. Safe and secure is what these provide me.

Just perfect puck locks

I have three cargo trailers with valuable equipment in them. Have used master hasp locks for years, and then saw these PROVEN INDUSTRIES PUCK LOCKS! Fit the latches perfectly and provide a sense of security. They are rather costly at $52/each, but well worth it.
