I was planning to have a manual pull down or electric screen on my wall 78 hX133 w inches. one problem is there is a window on this wall and the crown molding is etched out an inch out.
i tried to look up on the internet for the screens available. I can only find up to 120 " diagonal manual or electrical. anything above this range is very expensive for me. I can spend upto $400 max. i am not interested in a fixed frame at this point.
I was looking at option to by an DC 12 V tubular motor DIY kit from RollerTrol (rollertrol dot com). i found this on EBAY search. I am not sure it will help me. I need to insert a long tube like PVC pipe into the motor shaft and mount it on both sides of the wall ( just like the shower curtain). I am not sure what knind of pipe to use. Plastic/aluminium. The width is 133 inch. I am wondering if this will cause to Sag in the middle after I install.
At this point I am about to drop my idea but thought to post this here so some one can point me in right direction.
