Step #1 Measure door opening width and height in feet and inches. This determines the size of door needed. The rough opening should be the same size as the door.

Step #2 Measure for sideroom: 3-3/4" is required on each side for installation of the vertical track for standard extension spring, standard torsion spring and EZ-SET Torsion Spring System, 5-1/2" for EZ-SET Extension Spring System.

Step #3 Measure area labeled “headroom” – distance between the top of the door opening (“jamb header”) and the ceiling (or floor joist). 10" is required for the standard extension spring or EZ-SET Extension Spring System. 12" is required for standard torsion spring and EZ-SET Torsion Spring System. If you have restricted headroom, special hardware is available. Additional headroom is required for installation of an automatic garage door opener. NOTE: If door height extends above the opening, the headroom measurement should be adjusted proportionately.

Step #4 Measure area labeled “backroom” – distance is measured from the garage door opening toward the back wall of the garage. Door height plus 18" is required. Additional back room may be required for installation of an automatic garage door opener.
