I know there are multiple threads on raising the drop, but I cant find any information on lowering the drop of this screen. I know you use the allen screws inside the screen, but my question is it possible to lower the screen by say another 6 inches or so? Elite sent me the instructions and it claims that the screen is set to its maximum drop but looking inside the casing there is at least another full rotation of black wrapped around the motor. Has anyone actually tried to lower it further? How much drop needs to remain wrapped on the motor?
