Headroom Requirement:
■
Headroom is space needed above top of door for door, overhead tracks
and springs. Measure to check that there are no obstructions within that
space (Fig. 3-A).
■
Refer to Table 3-A for standard headroom requirements.
■
Track radius can be determined by measuring dimension “R”
(Fig. 3-B).
• If “R” equals 11" to 12", it is a 12" radius track.
• If “R” equals 14" to 15", it is a 15" radius track.
■
Determine which type of spring you have (STEP 4).
NOTE: If there is restricted headroom, several low headroom remedies
are available (Table 3-B). Installation of these options differ from
installation of a standard headroom door.
Supplemental instructions are included with hardware of each low
headroom option.
Rough Opening:
■
Rough opening (minus stop mold) = same size as door (Fig. 3-A)
Backroom Requirement:
■
Measured from back of door into garage, and should be at least
18" more than height of garage door (Fig. 3-A).
Sideroom Requirement:
■
Minimum 3-3/4" is needed on each side of door on interior wall surface
to allow for attachment of vertical track assembly.
■
Minimum 4-1/2" is needed on each side of door above opening for
torsion spring attachment.
NOTE: If you are installing an automatic opener, about 3" of additional
headroom at the center plus additional backroom is needed. Check
door opener instructions.
