Fasten Door Bracket

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

_!_:_: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

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