INSTALLATION STEP 12
Fasten the Door Bracket
Follow instructions which apply to your door type
as illustrated below or on the following page.
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.
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 Step 13.
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 1/4"-14x5/8" self-threading screws
(Figure 2A).
• Alternately, use two 5/16" bolts, lock washers and nuts
(not provided) (Figure 2B).
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"x2" 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.
