Whether you are replacing an existing door or pricing doors for a new garage, you must measure properly to be sure you order the right size. The illustrated instructions below explain the process.
Step #1
Measure the width and height of the door opening in feet and inches. You will need a door the same size as this rough opening.
Step #2
Measure for sideroom. You will need 3 ¾" on each side to install the vertical track for standard extension springs, standard torsion springs, or the EZ-Set Torsion Spring System™. For an EZ-Set Extension Spring System™, you will need 5 ½".
