To Install Header Bracket
Note: Installation procedures may vary according to door
type.
1.
While inside your garage, close the door and mark the
vertical centerline of the garage door. Extend the line onto
the header wall above the door spring.
2.
Open the door to the highest point of travel. Mark a line on
the header wall 2“ (5cm) above the highest point of travel.
Note: DO NOT install the Header Bracket over drywall. In some
installations, it may be necessary to install a 2x4 across two wall
studs to create a suitable location for the Header Bracket.
If installing into masonry, use concrete anchors (not provided).
