Installation Step 11

Fasten Door Bracket

Follow instructions which apply to your door type as illustrated below or on page 25.

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"-shapedsupport. The best solution is to check with your garage door manufacturer for an opener installation door reinforcement kit.

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.
