Install the Header Bracket
You can attach the header bracket either to the wall
above the garage door, or to the ceiling. Follow the
instructions which will work best for your particular
requirements. Do not install the header bracket
over drywall. If installing into masonry, use
concrete anchors (not provided).
WALL HEADER BRACKET INSTALLATION
• Center the bracket on the vertical centerline with
the bottom edge of the bracket on the horizontal
line as shown (with the arrow pointing toward the
ceiling).
• Mark the vertical set of bracket holes. Drill 3/16"
pilot holes and fasten the bracket securely to a
structural support with the hardware provided.
CEILING HEADER BRACKET INSTALLATION
• Extend the vertical centerline onto the ceiling as
shown.
• Center the bracket on the vertical mark, no more
than 6" from the wall. Make sure the arrow is
pointing away from the wall. The bracket can be
mounted flush against the ceiling when clearance
is minimal.
• Mark the side holes. Drill 3/16" pilot holes and
fasten bracket securely to a structural support with
the hardware provided.
