the door is guided to a central location as it closes. See Figure F below.
Dimension B should be: Dimension A plus 20mm (10mm each side).
•
Also ensure the tracks are angled back as shown in Figure G below. Dimension D
should be: at least Dimension C plus 25mm; or as far back as the slots in the top
TL bracket will allow. If the tracks are not angled back, the door seals will be
rubbing all the time.
