INSTALLATION STEP 10
Fasten Door Bracket and Plate
Follow instructions which apply to your door
type as illustrated below.
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. Exercise care in removing and
assembling arm conversion kit. Keep
fingers away from the sliding parts.
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. IIf yours is a canopy or dual-track style garage door, a door arm conversion kit is required. Follow
the installation instructions included with the replacement door arm.
