How To Measure a Door
Measure the Width (1) and Height (2) of your door opening in feet and inches.
The rough opening should be the same size as the door.
Measure the area labelled Left Side (3) and Right Side (4). For the installation of a standard torsion spring system, a minimum of 3-3/4” is required on each side of the vertical track.
Measure the area labelled Headroom (5).
This is the distance between the top of the door opening and the ceiling. 12" is necessary for a standard torsion spring system.
If the headroom is restricted, specialized hardware is available. We require additional headroom for the installation of an automatic garage door opener.
Please Note: If the garage door height extends above the opening, the headroom measurement should be adjusted proportionately.
Measure the area labelled Backroom (6).This is the distance from the garage door opening to the back wall of the garage. Door height must be 18" or more.
Please Note: Additional backroom may be necessary for the installation of an automatic garage door opener.
