INSTALLATION STEP 8
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 9.
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
l
two 1/4"-14x5/8" self-threading screws (Figure 2A).
Alternately, use two 5/16" bolts, lock washers and nuts (not
l
provided) (Figure 2B).
Metal, insulated or light weight factory reinforced doors:
Drill 3/16" fastening holes. Secure the door bracket using the
l
self-threading screws (Figure 3).
Wood Doors:
Use top and bottom or side to side door bracket holes. Drill
l
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.
