Just purchased this pop up A frame with Dormer. When open and shower up, the right side of the shower wall can tilt pretty far to the right. There are two clasps on each shower wall that are the same as the locking ones on the curtain install. It seems to me that they would make a rod attachment of some sort to steady the shower walls since they have the claps factory installed. Has anyone seen this? Any recommendations on how to make one if not factory?
