Installation	Step 11
Fasten Door Bracket
Follow instructions which apply to your door		To prevent damage to steel, aluminum,
		fiberglass	or glass panel doors, always
type as illustrated	below or on page 25.
		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.
