Use the drawing and instructions to measure your existing garage door. Take these measurements to your local installing dealer or retailer to purchase the Clopay® garage door that is right for you.
Measure the width and height (1 and 2) of your door opening in feet and inches to determine the garage door size you need. The rough opening should be the same size as the door.
Measure area labeled sideroom left and right (3 and 4) - a minimum 3-3/4" is required on each side for installation of the vertical track for a standard extension spring, standard torsion spring and the EZ-SET® Torsion Spring System; 5-1/2" for the EZ-SET® Extension Spring System.
