INSTALLATION STEP 8
Fasten Door Bracket and Plate
Follow instructions which apply to your door type
as illustrated below.
TO PREVENT DAMAGE TO LIGHTWEIGHT
AND METAL GARAGE DOORS (OR THOSE
WITH GLASS PANELS),
ALWAYS REINFORCE THE INSIDE OF DOOR—
BOTH VERTICALLY AND HORIZONTALLY—WITH
2X4
BOARDS OR ANGLE IRON.
The horizontal brace should be at least six feet long. The vertical brace should cover height of top panel. The best solution
is to check with the garage door manufacturer for a door reinforcement kit to be used with an opener installation.
