REPAIR / REPLACE BROKEN DOOR MOUNT
Some garage doors are installed equipped with a standard small door mounting bracket without vertical struts and some are actually even installed without either. It connects the two-arm of your opener to the garage door top panel connected by a cotter pin. Over time and usage stress is placed in the small area of the top of your door where this door mount is located causing your door panel to flex, bend, or split.
To save your door from this problem, a heavy duty Operator Reinforcement Bracket is recommended in place of the standard door mount. It may be a necessary accessory to help prevent dents/cracks to your top panel during their job in pulling up or pushing down the garage door in motion, especially for a double garage door with windows.
Replacing the standard or missing mount will help extend the life of your door panel and make your garage door operate smoother.
