Therma-Tru provides a simple tutorial on how to discover the handing of a door unit. Stand facing away from the door, and extend arms. The hand touching the hinge side is the handing of the door unit. For example, if the left hand is touching the hinge side then the door is a left handed door. Feel free to contact Therma-Tru with questions or concerns about maintaining a door unit.
