Sliding Glass Doors
Locate the adjustment hole on the side of the door panel's bottom edge (it may be concealed by a weather strip). Insert a hex key and turn it clockwise to raise the door panel; adjust both sides in tandem to ensure the door remains level. Finally, slide the door back and forth repeatedly to verify smooth operation without sticking.
Floor-Spring Hinged Doors
Pry open the stainless steel floor cover plate to access the floor spring's adjustment screws. Use a hex key to turn the screw clockwise to raise the door panel. Test the effect after every quarter-turn to avoid applying excessive force, which could cause the floor spring to leak oil.
Hinge or Clamp-Mounted Glass Doors
Loosen the fixing screws on the hinges or clamps. Support the glass while adjusting it to the desired height, then retighten the screws. If a significant height adjustment is required, a thin metal shim can be inserted at the hinge point to help raise the door.
