Can i adjust fabric height on outer bars?
I see 1 screw on top & 1 on bottom, with 12mm space to slide fabric up, if possible.
This would correct sagging from installation pitch.
Yes. You can pull the full 236” the main post is in the middle and the two retention posts are 118” on either side of the main post. I have 4 of them to provide privacy around my pool cage. Highly recommend.
