STEP 3 – Check Headroom/ Backroom/
Sideroom
Headroom is the space needed above the top of the door for
the door, the overhead tracks, and the springs. Measure to
check that there are no obstructions in your garage within that
space. The normal headroom space requirement is shown in
Table 3-A. The backroom distance is measured from the back
of the door into the garage, and should be at least 18" more
than the height of the garage door. A minimum sideroom of
3-3/4" (5-1/2" for EZ-Set™ Extension Spring) should be
available on each side of the door on the interior wall surface
to allow for attachment of the vertical track assembly. The
rough opening should be the same size as the door. (FIG. 3-A)
Track Radius: The radius of your track can be determined by
measuring the dimension “R” in FIG. 3-B. If dimension “R”
measures 11" to 12", then you have a 12" radius track. If “R”
equals 14" to 15", then you have a 15" radius track. (FIG. 3-B)
Headroom requirements
The standard headroom space requirement is shown in Table
3-A at right. (See page 8 if you have a question on which type
of spring you have.)
Low Headroom? If you have restricted headroom, several
remedies are available. See Table 3-B for various options.
NOTE: Installation of the various Low Headroom Options
differs from the installation of a standard headroom door.
Supplemental instructions are included with the hardware of
each Low Headroom Option.
