Determine the mounting option that works best for your
application and follow installation steps below:
1. Raise the Opener and rail assembly and temporarily place it
on a stepladder.
2. Position the Opener and rail assembly so that it is aligned to
the center line of the garage door. If the Header Bracket
was mounted off center, align the Opener with the Header
Bracket.
3. Measure the distance from each side of the Opener to the
structural supports.
4. Cut both Hanging Brackets* to appropriate length
*(Hanging Bracket not included)
5. Drill 3/16" holes in the structural supports.
6. Secure one end of each of the Hanging Brackets to the

each side with a 5/16"-18x1" Bolt and Flange Nut
