Hanger Type II
Figure I
Figure I shows the back of the screen. The hangers are affixed to the screen at the outermost 2 folds. The center fold is held straight by a simple bracket that clips on top of the screen. The red dots in the picture denote the holes in the hangers through which a picture wire or screw can be threaded to either hang the screen or affix it to the wall.
If your screen is less than 3'1" / 92.5cm tall, you may need to cut the top of the hangers to stop them protruding over the top of your screen.
Figure II
From the front, the hanging system is very inconspicuous. Look at the frame where the panels join and you may be able to spot the hanging brackets.
