INSTALLATION STEP 11
Fasten the Door Bracket
Follow instructions which apply to your door type
as illustrated
b
elow 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
b
race. For the
v
ertical
b
race, 2 pieces of
angle iron are used to create a U-shaped support.
The
b
est 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 12.
