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.
