How Do These Darn Things Stay Up?

Thank you everyone for the great support for my Galley Wing Walls, I sure do appreciate it! On that note, here is a video which I hope will help clarify the way they attach, setup, break down and stow away. On the video I erroneously stated that the hatch will not stay open with the wing walls up....ooops, I meant that the hatch will not CLOSE with the wing walls up because of the dowel and fabric.
