Ultra Thin Photo Frame Hanger (French Cleat)

I wanted to make sure that I could mount my photo frames as tightly to the wall as possible. I designed this thin french cleat at only 3mm thick. It's the same width as the folding part of the table stand, so it sits as close ans physically possible to the wall for my frame. 

To use, super glue the side of the cleat with no holes to the frame. The side with holes uses tiny pin nails to mount it to the wall.
