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).

• 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 (do not use the
holes designated for ceiling mount). Drill 5 mm pilot
holes and fasten the bracket securely to a structural
support with the hardware provided.
