'
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.
