Latches on exterior nesting boxes

[NellaBean]

What do you guys use for latches on your exterior nesting boxes? I will be putting a lock on mine as well (raccons

) but not sure what to use as a "latch".

Pictures?

How does your nest box open? Does the top lift up, as is most common, or does the front face open?

As requested, here are pictures of my nest boxes, the lid of which I secure with a hasp and lock.

Sillybirds, mine will be nearly identical to yours, just a bit wider. Thanks for the pics, I love the way you have yours set up.
