Installation Step 11
Fasten Door Bracket
Follow instructions which apply to your door
type as illustrated below or on page 25.
^ CAUTION
To prevent damage to steel, aluminum,
fiberglass or glass panel doors, always
reinforce the Inside of the door both vertically
and horizontally with an angle Iron.
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. Note correct UP placement, as
stamped inside the bracket.
• 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 5/16" left and right fastening holes.
Secure the bracket as shown in Figure 1 if there is
vertical reinforcement.
If your installation doesn't require vertical reinforce­
ment but does need top and bottom fastening holes
for the door bracket, fasten as shown in Figure 2.
