The ‘top hung’ system is most often used. The door is hung by two trolley hangers at the top of the door running in a concealed track; all the weight is taken by the hangers, making the door easy to move. At each end is a track stopper to absorb any impact made if the door is slammed and to hold the door in the open or closed position. All top hung Sliding Doors
gear systems have a maximum weight limit per pair of trolley hangers. When specifying a suitable sliding system the estimated weight of the door is a critical factor, although most suppliers of sliding door gear can advise on door weights.
As the door is hung at the top from two points, it needs additional guides at the bottom to prevent it from swinging sideways. The most common type is called ‘clear threshold guiding’, a floor-fixed plastic guide about 60 mm wide which is fixed below the door at the mid-point of its run. A groove is cut into the bottom of the door which runs over this guide, preventing lateral movement of the door. With a glass door the panel runs through the guide as illustrated. Because the door is always engaged in the guide, when the door is open the floor is clear, hence clear threshold.These doors are manufactured with G.I Steel or Stainless steel
