Installation
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.
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 the
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 between the door
panel support and the door bracket:
Drill 3/16" fastening holes. Secure the door bracket using the two self threading
l
screws. (Figure 1)
Alternately, use two 5/16"-18x2" bolts, lock washers and nuts (not provided).
