The sliding door is secured by a locking mechanism in a closed position wherein the sliding panel is held against a frame. When the locking mechanism is released, the weight of the sliding door causes the panel to move away from the frame while tilting the wheels in which the sliding panel slides into tilted positions. The panel is then free to roll along guide rails on the tilted wheels. When in the closed position, seals on the movable panel seal against the frame. During travel of the panel, the seals are in spaced relation to the frame. |
