Installation Step 1
Determine Header Bracket Location
Installation procedures vary according to
garage door types. Follow the instructions
which apply to your door.
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 30). 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
Vertical -- Ceilin -- garage door service.
