Backhang Requirements
Important Note: All doors over 12' high require
two backhangs evenly spaced on each hori-
zontal track. (FIG. 5-T) Also, all low headroom
track doors, all doors 12' high and under that
are over 600 lbs. or have 1" of sag in horizontal
track when the door is in full open position, will
require two backhangs evenly spaced on each
horizontal track.
Inspection of horizontal track is required after
completion of garage door installation. With the
garage door in the full open position, there
should only be
1
/4" of freeplay in rollers and
1
/2" from the edge of the horizontal track to the
edge of the door. (FIG. 5-T) Realign tracks if
necessary.
