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 bracket; proceed to Installation Step 12.

SECTIONAL DOORS

•Center the door bracket on the previously marked vertical centerline used for the header bracket

installation. Note correct UP placement, as stamped inside the bracket (Figure 2).

•Position the bracket on the face of the door within the following limits:

A)The top edge of the bracket 2"-4" (5-10 cm) 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.
