Fasten The Door Bracket - Craftsman CMXEOCG781 Owner's Manual

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 two 1/4"-
l
14x5/8" self-threading screws. (Figure 2A)
Alternately, use two 5/16"-18x2" 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 self-
l
threading screws. (Figure 3)
Wood doors:
Use top and bottom or side to side door bracket holes. Drill 5/16" holes
l
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.
