How to Adjust an Anderson Double Door

Anderson double doors are adjustable both horizontally and vertically. Make horizontal adjustments first as this corrects most problems. Vertical adjustments are necessary in few cases. A horizontal adjustment moves the panels side to side to square and center the panels in their opening. It adjusts the gap between the panels and the hinge side of the frames. The gap between the panels and the hinges should look equal; an adjustment is necessary when it does not. The vertical adjustment moves the panels up and down to center it in the opening. It equalizes the gap between the panels and the head or the sill.
