1Determine the header bracket
location
To prevent possible SERIOUS INJURY or
DEATH:
• Header bracket MUST be RIGIDLY
fastened to structural supporton header
wall or ceiling, otherwise garage door might
NOT reverse when required. DO NOT
install header bracket over drywall.
• Concrete anchors MUST be used if
mounting header bracket or 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
outof balance.An unbalanced garage
door might NOT reverse when required.
Installation
Installation procedures vary according to garage door types.Followthe instructions which apply to your
door.
1.1 Close the door and mark the inside vertical centerline of the 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 bracketon a 2x4 (on wall or ceiling), use lag screws(not
provided) to securely fasten the 2x4 to structural supports.
1.3 Open your door to the highest point 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 point for sectional door and one-piece door with track.
• 8" (20 cm) above the high point for one-piece door without track. This height will provide travel
clearance for the top edge ofthe 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.

7Attach the emergency release rope and handle
To prevent possible SERIOUS INJURY or DEATH from a falling garage door:
• If possible,use emergencyrelease handle to disengage trolley ONLY when garage door is
CLOSED.Weak or broken springs or unbalanced door could resultin an open door falling
rapidlyand/or unexpectedly.
• NEVER use emergency release handle unless garage doorway is clear of persons and
obstructions.
• NEVER use handle to pull door open or closed. Ifrope knot becomesuntied, you could fall.
7.1 Insert one end ofthe emergency release
rope through the handle. Make sure that
“NOTICE” is rightside up. Tie a knotat
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.

Fiberglass, aluminum or lightweight steel garage doors WILLREQUIRE reinforcement BEFORE
installation of door bracket.Contact your door manufacturer for reinforcement kit.
Figure 1 shows one piece of angle iron asthe horizontal brace.
For the vertical brace,2 pieces ofangle iron are used to create a
U-shaped support. The bestsolution 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.

Metal or light weight doors using a vertical angle iron brace between the door panel support
and the door bracket:
• Drill 3/16" fastening holes. Secure the door bracketusing the two self threading screws (H16).
(Figure 2)
• Alternately, use two 5/16" bolts, lock washers and nuts (not provided). (Figure 3)
Metal, insulated or light weight factory reinforced doors:
• Drill 3/16" fastening holes.Secure the door bracketusing the self-threading screws(H16).
(Figure 4)
