Installation Step 11

Fasten Door Bracket & Plate

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.

• 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, position the door plate over the

door bracket as shown in Figure 2. Fasten securely

with hardware shown in Figure 1.
