Our shower door hangs down and I have to pull up on the door to make it open and shut. I do not know what video is available to view, unable to locate the video. The right side of the door is the low side. It is a frameless type. There is only a metal strip on the left side with 1 screw at the top and bottom. I can lift the glass door up and the screws go with it! I have tried tightening them, but to no avail.
