Hello! To install the 39-310 clip, you will need to slip it onto the underside/inside of the glass louver. Both ends on the clip have an angle bent in opposite directions; one end catches the top edge on the inside of the glass, and the other end catches the inside bottom end of the metal louver clip. See the diagram below.
