STEP 1 Determine the Header Bracket Location
To prevent possible SERIOUS INJURY or DEATH:
lHeader bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling, otherwise
garage door might NOT reverse when required. DO NOT install header bracket over drywall.
lConcrete anchors MUST be used if mounting header bracket or 2x4 into masonry.
lNEVER try to loosen, move or adjust garage door, springs, cables, pulleys, brackets, or their hardware,
ALL of which are under EXTREME tension.
lALWAYS 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 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 of the garage door.
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 (see page 16) 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 securely
fasten the 2x4 to structural supports as shown here and on page 16.
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:
l2" (5 cm) above the high point for sectional door and one-piece door with track.
l8" (20 cm) above the high point for one-piece door without track.
This height 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 16 for ceiling
installation.

STEP 6 Attach the Emergency Release Rope and Handle
To prevent possible SERIOUS INJURY or DEATH from a falling garage door:
lIf 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.
lNEVER use emergency release handle unless garage doorway is clear of persons and obstructions.
lNEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall.
1. Insert one end of the emergency release rope through the handle. Make sure that “NOTICE” is right
side up. Secure with an overhand knot at least 1" (2.5 cm) from the end of the rope to prevent
slipping.
2. Insert the other end of the emergency release rope through the hole in the trolley release arm.
Mount the emergency release within reach, but at least 6 feet (1.83m) above floor, avoiding contact
with vehicles to prevent accidental release and secure with an overhand 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
entanglement.

Installation
STEP 7 Install the Door Bracket
Fiberglass, aluminum or lightweight steel garage doors WILL REQUIRE reinforcement BEFORE installation
of door bracket. Contact the garage door manufacturer or installing dealer for opener reinforcement
instructions or reinforcement kit. Failure to reinforce the top section as required according to the door
manufacturer may void the door warranty.
A horizontal and vertical reinforcement is needed for lightweight garage doors (fiberglass, aluminum, steel,
doors with glass panel, etc.) (not provided). A horizontal reinforcement brace should be long enough to be
secured to two or three vertical supports. A vertical reinforcement brace should cover the height of the top
panel. Contact the garage door manufacturer or installing dealer for opener reinforcement instructions or
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.
OPTION A - SECTIONAL DOORS
1. Center the door bracket on the previously marked vertical centerline used for the header bracket
installation. Note correct UP placement, as stamped inside bracket.
2. Position the top edge of the bracket 2"-4" (5-10cm) below the top edge of the door, OR directly
below any structural support across the top of the door.
3. Mark, drill holes and install as follows, depending on your door’s construction.
Metal or light weight doors using a vertical angle iron brace in the door panel support and the door
bracket:
lDrill 3/16" fastening holes. Secure the door bracket using the two 1/4"-14x5/8" self-threading
screws. (Figure1)
lAlternately, use two 5/16"-18x2" bolts, lock washers and nuts (not provided). (Figure2)
Metal, insulated or light weight factory reinforced doors:
lDrill 3/16" fastening holes. Secure the door bracket using the self-threading screws. (Figure3)
Wood doors:
lUse top and bottom or side to side door bracket holes. Drill 5/16" holes through the door and
secure bracket with 5/16"-18x2" carriage bolts, lock washers and nuts (not provided). (Figure4)
NOTE: The 1/4"-14x5/8" self-threading screws are not intended for use on wood doors.
