INSTALLATION STEP 10
Fasten Door Bracket
Follow instructions which apply to your door
type as illustrated below.
TO PREVENT DAMAGE TO LIGHTWEIGHT
AND METAL GARAGE DOORS (OR ONES
WITH GLASS PANELS), ALWAYS REIN-
FORCE THE INSIDE OF DOOR , BOTH
VERTICALLY AND HORIZONTALLY, WITH
ANGLE IRON OR 25mm BOARDS.
The horizontal brace should be at least 1.8m long. The vertical brace should cover height of top panel. The best
solution is to check with your garage door manufacturer for a door reinforcement kit for an opener installation.
