Determine “highest point of door travel”:1. Get on a ladder to the side of your garage door.2. Have someone lift the door open slowly.3. As the door is raised, find the highest point where the door extends above the door tracks—that isthe highest point of door travel. For sectional doors this is typically where the top door roller exits thecurved portion of the track onto the horizontal section as the door is raised.4. With a tape measure, determine the distance from the highest point of door travel to the floor.3b. Place a mark on the header at the highest point of door travel, preferably at the center of the door (mea-sured side to side).3c. Position the header bracket above the highest point of travel:· 2-1/2" above for sectional (hinged) doors.· 6" above for one-piece (non-hinged) doors.3d. Drill 5/32" pilot holes in header and secure bracket with 5/16" x 1-3/4" lag screws.Highest Point of door travel typical InstallationWA R N I N GDoor springs are under high tension.
