1 Determine the header bracket
location
To preventpossible SERIOUS INJURY or
DEATH:
• Header bracketMUSTbe RIGIDLY
fastened to structural supporton header
wall or ceiling, otherwise garage door might
NOTreverse when required. DO NOT
install header bracket over drywall.
• Concrete anchors MUSTbe used if
mounting header bracketor 2x4 into
masonry.
• NEVER try to loosen, move or adjust
garage door, springs, cables, pulleys,
brackets, or their hardware, ALL of which
are under EXTREME tension.
• ALWAYS call a trained door systems
technician if garage door binds, sticks,or is
out of balance. An unbalanced garage
door might NOT reverse when required.
Installation
Installation procedures varyaccording to garage door types. Follow the instructionswhich applyto your
door.
1.1 Close the door and mark the inside vertical centerline ofthe garage door.
1.2 Extend the line onto the header wall above the door.
You can fasten the header bracket within 4 feet (1.22 m) of the left or right of the door
center only if a torsion spring or center bearing plate is in the way; or you can attach it to
the ceiling when clearance is minimal.(It may be mounted on the wall upside down if
necessary, to gain approximately 1/2" (1 cm).
If you need to install the header bracket on a 2x4 (on wall or ceiling),use lag screws (not
provided) to securelyfasten the 2x4 to structural supports.
1.3 Open your door to the highestpoint oftravel as shown. Draw an intersecting horizontal line on
the header wall 2" (5 cm) above the high point.
• 2" (5 cm) above the high pointfor sectional door and one-piece door with track.
• 8" (20 cm) above the high point for one-piece door withouttrack.This heightwill 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 13 for ceiling
installation.

7 Attach the emergency release rope and handle
To preventpossible SERIOUS INJURY or DEATH from a falling garage door:
• If possible, use emergency release handle to disengage trolley ONLY when garage door is
CLOSED. Weak or broken springs or unbalanced door could result in an open door falling
rapidly and/or unexpectedly.
• NEVER use emergency release handle unless garage doorwayis clear of persons and
obstructions.
• NEVER use handle to pull door open or closed.Ifrope knotbecomesuntied,you could fall.
7.1 Insert one end of the emergency release
rope through the handle. Make sure that
“NOTICE” is right side up. Tie a knot at
least 1 inch (2.5 cm) from the end of the
emergency release rope.
7.2 Insert the other end of the emergency
release rope through the hole in the
trolley release arm. Make sure the
handle is 6 feet (1.83 m) above the floor
and secure with a knot.
NOTE: If it is necessary to cut the emergency
release rope, seal the cut end with a match or
lighter to prevent unraveling. Ensure the
emergency release rope and handle are
above the top of all vehicles to avoid

Fiberglass,aluminum or lightweightsteel garage doors WILLREQUIRE reinforcement BEFORE
installation of door bracket.Contactyour door manufacturer for reinforcement kit.
Figure 1 showsone piece of angle iron as the horizontal brace.
For the vertical brace, 2 pieces of angle iron are used to create a
U-shaped support. The best solution is to check with your garage
door manufacturer for an opener installation door reinforcement
kit.
NOTE: Many door reinforcement kits provide for direct attachment
of the clevis pin and door arm. In this case you will not need the
door bracket; proceed to the next step.
