A shower door assembly is provided with a shower door pane, and a track with a side opening. A pair of wheels is mounted for rotation upon the shower door pane. Each of the pair of wheels is sized to be received in the track for translation along the track. A diameter of each of the pair of wheels is greater than a vertical dimension of the side opening to prevent removal of the pair of wheels from the track while in a vertical orientation, and to permit the pair of wheels to be removed in an angled orientation.
