INSTALLING THE HEADER BRACKET
See Figures 29 - 31.
WARNING:
To avoid serious personal injury, attach header bracket to
sound structural support on header wall. NEVER install
the header bracket into weak surfaces such as drywall
that can cause the header bracket to fall.
WARNING:
ALWAYS use lag screws and concrete anchors (not
included) when installing the header bracket or 2x4 into
concrete, brick, or other masonry. Failure to properly
install the header bracket and associated hardware can
result in a falling object hazard and result in death or
serious personal injury.
WARNING:
Only install screws, bolts, anchors, and other hardware
into sound structural supports in areas where no electrical
wires, utility cables, pipes, or other obstructions are
located. Contact your local utility company or a qualified
electrician if you are unsure. Ensure all hardware
components are securely installed to prevent falling
objects. Failure to follow these instructions can result in
death, electrical shock, or other serious personal injury.
Always install the header bracket onto a sturdy surface. The
force required to raise and lower the garage door could pull
the bracket and mounting hardware out of weak surfaces
such as drywall. For some installations, it may be neccesary
to create a suitable location for the bracket by installing a
