If there are no suitable mounting surfaces to mount the
opener, a strong mounting support will be needed.
Securely fasten a wood (2" x 6" recommended)
mounting surface for the opener. Make sure it is flush
with the header and located to allow the opener to
secure to it. Install the adjustable wall bracket to the
studs in the wall plate. Loosely secure with the 5/16-
18 nuts and lock washers provided.
IMPORTANT! This opener will not install properly
on doors with offsets other than 3-3/8” and 2-1/2”.
