• Open your door to the highest
point of travel as shown. Draw
an intersecting horizontal line
on the header wall 2" above
the high point. This height will
provide travel clearance for the
top edge of the door.

• Close the door and mark the inside
vertical centerline of the garage door.
• Extend the line onto the header wall
above the door.
Remember, you can fasten the
header bracket within 2 feet to 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 (refer to page 12)
when clearance is minimal. (It may
be mounted on the wall upside down
if necessary, to gain approximately
1/2".)

If you need to install the header bracket

on a 2x4 (on wall or ceiling), use lag

screws (not supplied) to securely fasten

the 2x4 to structural supports as shown

here.

Installation Section: Pages 11 – 23Installation Step 1

Determine Header Bracket Location

If the header bracket is not rigidly fastened to
a structural support on the header wall or
ceiling, the safety reverse system may not
work properly (see page 26).

The door might

not reverse when required, and could cause

serious injury or death.
The garage door springs, cables, pulleys,
brackets and their hardware are under extreme
tension.

Do not attempt to loosen, move or

adjust them yourself. Serious personal injury

or death could result.

Call for garage door
service.
