INSTALLATION
Draw a bisecting horizontal line above the high point:
• For sectional or single-panel garage doors with tracks,
the line should be approximately 2 in. 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 20.

of Travel
To install the bracket to the header wall:
Lower the garage door completely.
Using a pencil and a level, draw a vertical line in the center
of the top portion of the garage door.
Continue drawing the center line from the door to the
header wall. Extend the line to about a foot above the
garage door or as far as possible.
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.
