Determine Header Bracket Location
Installation procedures vary according to garage
door types. Follow the instructions which apply to
your door.
Proceed to Step 2, page 10.
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
professional garage door service.
Remember, you can fasten the header
bracket within 2 feet 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
(refer to page 10) 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 and on
page 9.
