Installation procedures vary according to garage door
types. Follow the instructions which apply to your
door.
SECTIONAL DOOR AND ONE-PIECE DOOR
WITH TRACK
1. Close the door and mark the inside vertical
centerline of the garage door.
2. Extend the line onto the header wall above the
door.
You can fasten the header bracket within 4 feet
(1.22 m) of the left or right of the door center
only if a torsion spring or center bearing plate
is in the way; or you can attach it to the ceiling
(see page 14) when clearance is minimal. (It
may be mounted on the wall upside down if
necessary, to gain approximately
1/2" (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
header watt 2" (5 cm) above the high point. This
height will provide travel clearance for the top edge
of the door.
NOTE: Door clearance brackets are available for
sectional doors when headroom clearance is less
than 2" (5 cm). See accessory page 39.
Proceed to Step 2, page 14.
