Figure 1 shows one piece of angle iron as the horizontal brace.
For the vertical brace, 2 pieces of angle iron are used to create a
U-shaped support. The best solution 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.
HARDWARE
A horizontal and vertical reinforcement
is needed for lightweight garage doors
(fi 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.

8.1A 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.
8.2A 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.
8.3A 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
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 bracket using the self-threading
screws (H16). (Figure 4)
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"x2" carriage bolts, lock washers and nuts
(not provided). (Figure 5)
NOTE: The 1/4"-14x5/8" self-threading screws are not intended for use on wood
doors.
