SPECIAL ADJUSTMENTS
Angular Adjustment
The jamb supports should be at a 90 degree angle from the face of the door. This can be checked using
a framing square. The jamb rack (aluminum extrusion with eight (8) jamb supports) can be rotated to
achieve the correct angle. To rotate the jamb rack, loosen the jamb nut on the adjustment link and rotate
the link. By shortening the link, the jamb is tilted toward the door (angle decreases). Lengthening the
link tilts the jamb away from the door (angle increases). When making this adjustment, be sure to check
and adjust both ends of the jamb rack.
