I screwed it to the door frame by drilling 4 small holes. One near each end at the bottom and one about 2" below the top just before it makes the bends. When I redo it, I may drill a hole either at the center of the bends or just after so those corners can be pulled in a bit tighter. The stuff is bendable, but I had a little trouble getting it tight in the corners. It did conform to the glass though. Hope this helps.
