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" (15 cm) 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.
