Check the Door
To prevent possible SERIOUSINJURYor DEATH:
ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An
unbalanced garage door may NOT reverse when required.
NEVER try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or their
hardware, ALLof which are under EXTREME tension.
Disable ALLlocks and remove ALLropes connected to garage door BEFORE installation and operating

Installation
STEP 8 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:
Drill 3/16" fastening holes. Secure the door bracket using the two 1/4"-14x5/8" self-threading screws.
(Figure1)
Alternately, use two 5/16"-18x2" bolts, lock washers and nuts (not provided). (Figure2)

Installation
STEP 9 Connect the Door Arm to the Trolley
Installation will vary according to the garage door type. Follow the instructions which apply to your door.
OPTION A - SECTIONAL DOORS
IMPORTANT: The groove on the straight door arm MUST face away from the curved door arm.
1. Close the door. Disconnect the trolley by pulling the emergency release handle.
2. Attach the straight door arm to the outer trolley using the clevis pin. Secure with the ring fastener.
3. Attach the curved door arm to the door bracket using the clevis pin. Secure with the ring fastener.
4. Bring arm sections together. Find two pairs of holes that line up and join sections. Select holes as far
apart as possible to increase door arm rigidity and attach using the bolts, nuts, and lock washers.
5. Pull the emergency release handle toward the garage door opener until the trolley release arm is
horizontal. The trolley will re-engage automatically when the garage door opener is activated.
NOTE: If the holes in the curved door arm and the straight door arm do not align, reverse the straight door
arm, select two holes (as far apart as possible) and attach using bolts, nuts, and lock washers. If the straight
door arm is hanging down too far, you may cut 6" (15 cm) from the solid end.
