Yup, the latch is on the left. I put some sort of sliding bolt in the hollow frame. There's a spot for a simple padlock as well. If I remember right I clad the masterlock in some banged up metal so it wasn't a big ole shiner. Kinda put a skirt on it. By the way, architects love the word "clad".
I would have liked to used solid material and traditional joinery and the whole nine, but the budget was,ummm, kind of weak. So we have to make do with what we get, right?
Thanks for the questions.
