Note: As the manual suggests if you already had a header bracket in place you can use it.

The first step in opener installation that our technicians at aaa Garage Door inc do is by installing the header brackets. which is the most important step because the header brackets are responsible to provide stability for the opener end of the rail, header brackets also help to ensure that the opener is installed at the proper height and angle above your garage door system for optimal performance. This is important because if the opener is installed too low or at the wrong angle, it can cause the door to operate improperly or even damage the door or opener.

Placing header brackets Steps
Get your stepladder.

Put a mark at the wall to the highest point that the first panel of the garage door reaches.

Close your garage door and above this mark by a minimum of 2 inches start placing the header brackets by making holes in the pilot holes using your drill.

Install the header brackets using the provided bolts with the proper size Socket Wrench.

Start hanging the opener in ceiling you need to prepare the perforated angle brackets (Hanging brackets & Support brackets ).

The support perforated angle support bracket will be installed in your ceiling

The hanging perforated angle brackets typically be included with the garage door opener package and will be used to hang the opener in the support bracket.

Install the support perforated angle brackets

Mark the location of the screw holes on the garage ceiling, and then use a drill to create pilot holes. Attach the support brackets using screws and bolts.

An expert technique that our technicians follow is when installing a garage door opener, it is generally recommended to install the support brackets to hang the opener on a place of studs for optimal support and stability.

In case of these studs are not exposed due to the garage door being enclosed with the Ceiling Drywall, so we use the studs finder device which is a device that helps to locate the studs using electronic sensors or magnets.

Install the hanging perforated angle brackets

Measure the distance between the support perforated angle brackets and the opener.

Open your garage door and put a wood piece under the opener rail, while the opener is mounted on your garage door you need to measure the proper distance between the support brackets and the opener.

Measure the hanging perforated angle brackets and cut to the measured distance.

Connect the hanging, support brackets and opener

Connect the hanging brackets to the support brackets then connect the opener to the hanging brackets.

Remove the wooden piece under your garage door opener rail and close your garage door.

Finalize The Opener Hanging

Remove the wooden piece under your garage door opener rail.

Close your garage door.

Install the emergency release rope to the trolley. As Manual instructions, Make sure the emergency release rope is at least 6 feet off the ground.
