Query: Masterlock 379DAT is NOT Universal

I have a 6 year old premium bass boat trailer with 2 inch coupler and surge brakes. The tongue style is UFP. This lock does not fit snugly against the tongue...it angles away with a 1.5 inch gap. Someone could easily get a pry bar between the lock and the tongue. A thief may not remove the lock but they will seriously damage the tongue. I am going to get stuck with $13 in wasted shipping returning this junk. Don't make the same mistake!
