6.4.1 How to wedge a curtain
Why would a curtain need a wedge?
A wedge is used to correct uneven curtain build, which can be evidenced by the following
symptoms:
(a) Bottom bar tracks to either right or left thereby causing it to jam against the guide,
(b) Bottom bar becomes out-of-level when door is in the open position,
(c) Curtain tends to 'cone' in one direction on the barrel, as the door is rolling up.
What is a wedge?
A wedge is a piece of waste rubber (can be as large as 6" square by as much as 1/2"
thickness), which is strategically placed on the drive barrel between the curtain and the
barrel. It is secured with a self-tapping screw(s).
How to determine where to fasten wedge.
It is normal for a curtain to 'float' slightly from side to side as the door rolls up and down.
Wedging is required only when there is a severe tracking problem such as listed above.
The placement of a wedge can be determined in several ways. For example, if the bottom
bar were tracking to the left as the door is opening, then the wedge would be fastened on the
right end of the barrel. The wedge would then make the curtain roll-up faster on the right
side, thus making the bottom bar track evenly between the guides. Should the door be
tracking to the right, and then obviously the wedge should be fastened to the left end of the
barrel.
It is important to identify whether a door requires a wedge or if it has been installed out-of-
level. For instance, if a door rolls down with the bottom bar continually tracking to one side,
eventually jamming near the floor, yet the curtain does not appear to 'cone', then the door is
most likely out-of-level. To remedy the problem, it may be necessary to raise one of the end
plates (which have slotted holes) to level the door.
