#54687, "RE: Vertical sliding Watertight Door system" In response to In response to 11
I see at least 3 ways to fix this: -two cylinders, one at each side of the door and a cross bar between them at the top of the door. Notch it to clear the door frame and release mechanism. -one cylinder beside the door and a lever from a pivot beyond it, across the piston rod and reaching the top center of the door. -hang the cylinder from the ceiling or a wall bracket so that there is space between it and the wall for the door to rise. A bracket at the bottom of the door would connect to the bottom of the piston rod.
