So it goes into a channel of some sort when closed? I bought a pleated one for mine. I love it. SOOOO much nicer than a shower curtain. I used colored caulking to hide the holes from the track in the ceiling. Notice, I also reversed the door in mine so it opens toward the bunk beds, not the refer. I did a literal flip of the door and the frame. It sits a little higher than it used to but still has a gap at the top and the bottom.
