Install Door Bracket To Door - Genie M-4500 Owner's Manual

8-2. INSTALL HEADER BRACKET (cont'd)
I Mark pilot holes location on header through holes where
lag screws will be inserted. IMPORTANT: See Fig. 11 for
which header bracket holes to use.
I Drill 3/16" pilot holes into header, and install bracket with
lag screws (5/16 x 1-5/8") provided.
I Tighten lag screws firmly.
NOTE: Follow the same procedure if header (shown in Fig.
11) runs vertically instead of horizontally and is the only
option for mounting header bracket to header wall. In case
of minimal clearance above the garage door, the header
bracket may be mounted to the ceiling. Follow the same
steps above to ensure a sound surface for mounting.
