Picture Frame Adjustable Hanger

We have some picture frames where the frame is so deep that the hanger is to far away from the wall to hang on the nail or screw...

So I quickly came up with this design that sticks to the inside of the frame and allows the frame to hang on a nail or screw. The teeth along the hanger help get the picture perfectly aligned on the wall.

It's probably been done before but sometimes it's just as quick to put your thoughts into sketchup and just print!
