Have a look at how 'warthog1981' has bolted on some picture hanging loops and made a removable handle in this thread.

Also how I used that same idea for holding a wire type handle in the same thread.(the wire handle being an idea I got from Wayland's hobo stove )
They make a neat alternative to holes. If I were to do it again I would probably use the smaller type hangers ( on right in picture). Would also mean drilling two less holes
