  • 13.4. Once you have adjusted the doors, make sure that each toe and heel plate is tight to the glass in each door, this will prevent the doors from settling over time.

14. Adjustment

NOTE: All adjustment comes from the outer frame.

Tracks

  • 14.1. To check the top and bottom tracks are parallel, open all the door leaves completely.
  • 14.2. At this point, the pins in the centre of the top guide wheel should be fairly flush with the visible face of the guide wheel, as shown in FIG14A. Move the doors along the track whilst monitoring the pins in the top guide wheels. If the top and bottom tracks are parallel, the visible pin should remain the same as at the start.
  • 14.3. If the visible pin decreases at any point, the top track will need repacking to raise it up at these points.
    Figure 14AFIG 14A
  • 14.4. If the visible pin increases at any point, the top track will need repacking to lower it at these points. NOTE: The bottom track must be well supported and level for the description above to be correct.
