We all use ammo boxes, I don't know any guy, especially a maker of any sort that does not. Once in a while I would like one that is, at least reasonably secure. having tried padlocks and cam locks and they blow. it came to me that locking hood locks were the answer. If everybody else in the world knew about this but me, just humor me, I think it worked pretty slick.
I welded a cross bar inside a 20 mm box and mounted the "strike in the center of it, actually I drilled down through the lid and the bar at the same time to make sure I got things plumb. the cover required a double D hole but those knock out dies are very expensive so I cut a rectangular hole with a Dremmel /thin cut off wheel. Adjust the strike up or down to the best latching position.
Looks slick and clean, as secure as I could hope for and two locks for $30.
I would post pictures but can't seem to find my way into the gallery.
This is the new console for my CJ5 just the right height and width fits just right between the Master crafts.
