INSTALLATION STEP 2

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 (do not use

the holes designated for ceiling mount). Drill 3/16"
pilot holes and fasten the bracket securely to a
structural support with the hardware provided.
