INSTALLATION  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. Header Bracket  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 13 mm socket. 2 in. above Highest Point of Travel Fig. 30 Header Bracket Lag Screws Fig. 31 23 - English
