I have a 2007 Big Horn 3055RL. On the "latch" side, as opposed to the hinged side, of the glass shower door there is a narrow, black rubber-like seal running from the top to the bottom near the edge of the door. The CEO found a half inch or so piece of that strip on the floor. The strip had slid down and the door could not be closed. I slid the strip back up and pushed the small piece in below the strip temporarily holding it in place. The small piece is irregular shaped as though it were broken or is that the way it was made. I can't figure out how else the strip is held in place. Can anyone offer any suggestions?
