INSTALLATION STEP 12
Fastenthe Door Bracket
Follow instructions which apply to your door type as illustrated
below or on the following page.
A horizontal reinforcementbrace shouldbe long enoughto be
securedto two or three vertical supports.A vertical
reinforcementbrace shouldcover 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.

of the clevis pin and door arm. In this caseyou will not need the
door bracket, proceed to Step 13.
