INSTALLATION STEP 1 1

Fasten the Door Bracket

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

A horizontal reinforcement brace should be long enough to be secured to two vertical supports. A vertical reinforcement 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, two pieces of angle iron are used to create a U-shaped support (Figure 1). The best solution is to check with your garage

door manufacturer for an opener installation door reinforcement kit.

NOTE: Many vertical brace installations provide for direct attachment of the clevis pin and door arm. In this case you will not need the door bracke# proceed to Installation

Step 12.
