Nice, I don't have room for that type as the ceiling light is in the way. I would have to open up the panel above the current door and fit a roller door where your diagonal panel sits, if there is height for it.
Actually I am confused by you picture and video. The picture shows the door just big enough for the height with 4 panels but the video shows more panels at 45 deg and horizontal as only 2 panels close. Does the video end before the door is fully closed?
I ask as obviously I have room on my ceiling to match the height of the current up an over but not if there needs to be extra panels than just the door height for a sectional door.
Is it possible to see a video of the last panels closing at the top?
