The invention provides a door system which has a door leaf with a first horizontally disposed edge and a second horizontally disposed edge inferior to the first horizontally disposed edge. The door system also includes a rod-less cylinder in communication with the first horizontally disposed edge and a cam surface formed with the second horizontally disposed edge. The cam surface limits the door to a single plane of movement relative to an opening of an enclosure defining a door jamb.
