I have a doorway that we are wanting to put a sliding glass door to let the light through into a dark hallway when closed in the basement (which has extremely low ceilings - roughly 6'2" in this hallway). I could use a regular door but it would have to open into a really small room and I would prefer not to use up the inside wall space to rest a door against. The problem is the ceiling height is abysmal at only having roughly 1" above the rough opening. As such, ceiling mounted hardware, or even wall mounted that runs along the top of the door frame, will not work. Does anyone know of hinges that can run along the side wall - kind of like a kitchen drawer that extends across the door way and then retracts inside itself as the door opens? Or another suggestion for hardware? Yes I can just have no door - but then if the small room becomes full of junk ... well we could not shut or slide a door to hide it :)
