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.
