When setting up a Fast-Fold screen, and you find you need it to be a few inches taller or shorter, but not a full crank-hole’s worth, remove the screen, rotate the surface 180°, and rotate the screen 180°. This will offset the cranks less than one set of holes and might get you where you need to be.
One drawback to this trick is that the dress kit won’t connect anymore because its’ connectors are now at the bottom of the screen.
