If your installation doesn't require vertical
reinforcement but does need top and bottom
fastening holes for the door bracket, fasten as shown
in Figure 2.
INSTALLATION STEP 11
Fasten the Door Bracket
A horizontal brace should be long enough to be
secured to 2 vertical supports. A vertical 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, 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.
• Center the door bracket on the previously marked
vertical guideline used for the header bracket
installation.
• Position the bracket on the face of the door within
the following limits:
A) The top edge of the bracket 2"-4" below the top
edge of the door.
B) The top edge of the bracket directly below any
structural support across the top of the door.
• Mark and drill 3/16" left and right fastening holes.
Secure the bracket as shown in Figure 1 if there is
vertical reinforcement.
