Planning

Identify the type and height of your garage door. Survey your
garage area to see if any of the conditions below apply to your
installation. Additional materials may be required. You may find it
helpful to refer back to this page and the accompanying
illustrations as you proceed with the installation of your opener.
Depending on your requirements, there are several installation
steps which may call for materials or hardware not included in the
carton.
• Installation Step 1 – Look at the wall or ceiling above the
garage door. The header bracket must be securely fastened to
structural supports.
• Installation Step 5 – Do you have a finished ceiling in your
garage? If so, a support bracket and additional fastening
hardware may be required.
• Do you have an access door in addition to the garage door? If
not, Model 1702E Outside Quick Release is required. See
Accessories page.
