STEP 1 Determine the header bracket location

To prevent possible SERIOUSINJURY or DEATH:

Header bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling, otherwise garage door might NOT reverse when required. DO NOTinstall header bracket over drywall.

Concreteanchors MUST be used if mounting header bracketor 2x4 into masonry.

NEVER tryto loosen, move or adjustgarage door, springs, cables,pulleys,brackets,or their hardware, ALL of which are under EXTREME tension.

ALWAYS call a trained door systemstechnician if garage door binds,sticks,or is out of balance. An unbalanced garage door might NOT reverse when required.

Installation procedures vary according to garage door types.Follow the instructions which apply to your door.

1. Close the door and mark the inside vertical centerline ofthe garage door.

2. Extend the line onto the header wall above the door.Youcan fasten the header bracket within

4 feet (1.22 m) of the left orright of the door center only if a torsion springor center bearing plate is in the way; or you can attach it to the ceiling (see page 12) when clearance is minimal. (It may be mounted on the wallupside down if necessary, to gain approximately

1/2" (1 cm). Ifyou need to install the header bracket on a 2x4 (on wall or ceiling), use lag screws

(not provided) to securely fasten the 2x4 to structural supportsas shown here and onpage 12.

3. Open your door to the highest point of travel as shown.Draw an intersecting horizontal line on the header wall 2" (5 cm) above the high point :

2" (5 cm) above the high point for sectional door and one-piece door with track.

8" (20 cm) above the high point for one-piece door without track.

Thisheight will provide travel clearance for the top edge of the door. NOTE: If the total number of inches

exceeds the height available in your garage, use the maximum height possible, or refer to page12 for ceiling installation.
