To prevent damage to garage door, reinforce inside of
door with angle iron both vertically and horizontally.
INSTALLATION STEP 10
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 vertical supports. A
vertical reinforcement brace should cover the
height of the top panel.
The illustration shows one piece of angle iron as the
horizontal brace. For the vertical brace, two pieces of
angle iron are used to create a "U"-shaped support
(Figure 1). The best solution is to check with your
garage door manufacturer for an opener installation
door reinforcement kit. If your door is a canopy or
dual-track style garage door, a door arm conversion
kit is required. Follow the installation instructions
included with the replacement door arm.
NOTE: Many vertical brace installations provide for
direct attachment of the clevis pin and door arm. In
this case you will not need the door bracket; proceed
to Installation Step 11.
