Kent,
Call Kent @ Catalina (california). He can help you.
I always thought the folding door was abit overkill, also some people are claustraphobic.
I replaced my door with a nice thick fabric shower-type curtain like you see in motel rooms. After cutting it to size, use the extra fabric and have some wraps made using snaps that ard mounted to the side frame to hold it in place when open. You can get fancy with the look as where you place the wraps. Just a suggestion.
