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 centertine 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 beating plate is in the way;
or you can attach it to the ceiling (see page t3)
when clearance is minimal. (It may be mounted on
the wall upside down if necessary, to gain
approximately 112" (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 t3
3. Open your door to the highest point of travel as shown.,
Draw an intersecting horizontal line on the header wall
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 height will provide travet clearance for the top edge
of the door°
NOTE: if the total number of inches exceeds the height
available in your garage, use the maximum height
possible, or refer to page I3 for ceiling installation,.
