door. If there is any question contact your Customer

The header is a heavily reinforced section of the wall just
above the top of the garage door opening.

above door. Draw a center line to connect points.

(Do not attach Header Bracket).
Raise door, watching top edge of door and stop door
when its edge reaches its highest point.
Measure distance ("H") from top edge of door to floor.
For sectional doors, add 2-1/2" to "H" . Mark a point
on center line. Bottom of Header Bracket will be
installed here.
For one-piece doors, add 6" to "H" . Mark this point on
center line. Bottom of Header Bracket will be
installed here.
For both types of doors:
– If the ceiling in your garage is so low that there is
not at least a 3" space above the Header Bracket
mounting point, contact a Genie Factory
Authorized Dealer.
If a door spring is in the way, place the Header
Bracket avove the spring. Do Not move the door spring.

Check wall for a stud or a solid header at your mark:
(If checking a finished wall, a stud finder may be helpful).
If location is above Header, a 2" x 6" board must be
screwed to studs beside your mark with at least two Lag
Screws and Flat Washers (not provided).
