During assembly, installation and adjustment of the

opener, instructions will call for hand tools as

illustrated below.

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.

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
