How to Adjust an Anderson Doorwall

If your Anderson doorwall slides stiffly or drags slightly, it is out of adjustment. It is important to maintain your doorwall to make sure it lasts as long as possible. Doorwall adjustment is necessary because of the settling of your house and temperature variations. Adjusting your doorwall is not a difficult task. It requires only simple hand tools.

      Adjust the locking mechanism on the door to ensure that it works properly by inserting a screwdriver into the adjustment screw on the lock. Turn the screwdriver counterclockwise to the “in” position to make the lock fit tighter. Turn the screwdriver clockwise to the “out” position for a looser fit.
