Honestly, I'm not 100% sure. There was a box of ammo at the bottom right where the single bottom bolt goes down, but the upper and lower "adjusters" for the closing side bolts were tweaked as well. I can't see how the 4x4 trick would have worked if it was the ammo (no marks on the plastic box) and after getting everything adjusted it really wasn't that far out of whack. All I know is the handle was tight as hell before cinching down the ratchets, and it got a little easier the tighter I cinched that block of wood. It opened right up with the code when I figured it was sufficiently loosened up. I've tried it several times since and it works like a champ!
