CAUTION
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 rein-
forcement 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 (berglass, 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 reinforce-
ment 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)
Metal, insulated or light weight factory reinforced doors:
Drill 3/16” fastening holes. Secure the door bracket using the self-threading screws. (Figure 3)
Wood doors:
Use 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.
