Use and Care Manual

23 - English
Stand on a ladder near the garage door as someone
slowly raises it. While it’s moving, find and mark the
highest point of travel along the center line. The high
point will vary based on the type and construction of your
garage door, but typically it will be 10-12 inches above
the top of the door.
WARNING:
Use extreme care when standing on a ladder. Ensure
someone is holding the ladder on the ground to keep it
stable. Failure to safely use a ladder can cause a fall and
result in death or serious personal injury.

INSTALLATION
Draw a bisecting horizontal line above the high point:
• For sectional or single-panel garage doors with
tracks, the line should be approximately two inches
above the high point.
• For single-panel garage doors without tracks, the
line should be approximately 8 in. above the high point.
 NOTE: The position of the horizontal line will determine
the clearance between the top of the door and the rail
assembly. If the height of your garage prohibits you from
drawing the line as specified above, draw it as far above
the high point as possible.
Orient the header bracket as shown in figure 31.
Place the bottom edge of the header bracket on the
horizontal line and center the bracket on the center line.
Mark the holes in the bracket.
Drill 3/16 in. pilot holes and secure the bracket in place
using lag screws. Install screws with a 1/2 in. socket.
