Installation procedures vary according to garage door types.
Follow the instructions which apply to your door.
1. Close the door and mark the inside vertical centerline of the
garage door.
2. Extend the line onto the headerwall abovethe door.
You can fastenthe header bracketwithin 4 feet (1.22 m) of
the left or right of the door center only if a torsionspringor
center bearing plate is in the way; or you can attach it to the
ceiling (see page 13) when clearance is minimal. (It may be
mountedon the wall upsidedown if necessary,to gain
approximately1/2" (1 cm).)
If you need to install the header bracket on a 2x4 (on wall or
ceiling), use lag screws (not provided) to securely fasten the
2x4 to structural supports as shown here and on page 13.
3. Open your door to the highest point of travel as shown. Draw
an intersecting horizontal line on the headerwall abovethe high
point:
• 2" (5 cm) abovethe high point for sectional door and
one-piece door with track.
• 8" (20 cm) abovethe high point for one-piece door without
track.
This height will provide travel clearancefor the top edge of the
door.
NOTE:If the total number of inches exceedsthe height available
in your garage, use the maximum height possible, or refer to
page 13 for ceiling installation.
