7. Adjustment Procedures
During normal operation, the tension pipes should run in close proximity of each other. The clearance between
the tension pipes should normally be between 1/4
″ to 1/2″ (6.35 mm - 12.7 mm). There are two situations
pertaining to the tension pipes that may cause problems with door operation. If the tension pipes are too far
apart, the tension pipes will not repel each other. This causes poor contact between the hook & loop. On the
other hand, if the tension pipes are riding one another (i.e. touching one another), the door curtain material does
not flow evenly, thus leaving wrinkles in the curtain instead of a stretched, smooth and even appearance.
The clearance between the tension pipes can be adjusted by raising or lowering the door curtains. Each door
has three curtains: (1) The inside curtain (curtain facing the inside of building) is attached to the back plate.
(2) The center curtain is attached to the drive pipe. (3) The outside curtain (facing the outside of building) is
attached to the top bar. Adjustments are made to the inside curtain and/or the outside curtain.
To adjust the height of the outside tension pipe, raise or lower the outside door curtain by detaching the curtain
from the top bar, and raising or lowering the curtain. Then re-attach the curtain loop to the hook on the top bar.
Be sure to keep tension pipe level during this procedure. Install pan head screws through the curtain and into
the top bar to securely hold the material in place. See the diagram below.
To adjust the height of the inside tension pipe, raise or lower the inside door curtain by detaching the curtain
from the back plate, and raising or lowering curtain. Then re-attach the curtain loop to the hook on back plate.
Be sure to keep tension pipe level during this procedure. Install pan head screws through the curtain and into
the back plate to securely hold the material in place. See the diagram below.
