Installation procedures vary according to garagedoor types.
Follow the instructions which apply to your door.
1. Closethe door and mark the inside vertical centerline of the
garagedoor.
2. Extendthe line onto the headerwall above the door.
Youcan fasten the header bracketwithin 4 feet (1.22 m) of
the left or rightof the doorcenter only if a torsion springor
center bearingplate is in the way; or youcan attach it to the
ceiling (see page 13) whenclearance is minimal. (It may be
mountedon the wall upsidedown if necessary,to gain
approximately1/2" (1 cm))
If you needto install the headerbracket on a 2x4 (on wall or
ceiling), use lag screws (not provided) to securely fasten the
2x4 to structural supports as shown hereand on page13.
3. Openyour door to the highest point of travel asshown. Draw
an intersecting horizontal line on the headerwall above the
high point:
• 2" (5 cm) above the high point for sectional door and
one-piece door with track.
• 8" (20 cm) above the high point for one-piece door without
track.
This heightwill provide travel clearancefor the top edgeof the
door.
NOTE:If the total number of inches exceedsthe height available
in your garage, use the maximum height possible, or refer to
