Mounting Header Bracket

To prevent SERIOUS INJURY:
- DO NOT connect power until instructed.
- The Header Bracket MUST be SECURELY fastened to the structural support on the mounting wall or
ceiling, otherwise the door may not reverse when required. DO NOT install the Header Bracket over drywall.
- Concrete anchors MUST be used when mounting the Header Bracket into masonry.
- NEVER try to loosen, move or adjust garage door springs, cables, Pulleys, Brackets, or hardware, all of
which are under EXTREME tension.

WARNING
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).
Wall-Mounting
As shown in Fig.2, place the Header Bracket on the vertical
centerline in direction shown.
Mark and drill two 3/16" holes. Fasten the Header Bracket
securely to a structural support using two 5/16" x 2-1/2" Lag
Screws.
Alternative Ceiling-Mounting
Ceiling-mounting is suggested ONLY when clearance is minimal.
Extend the vertical centerline onto the ceiling as shown in Fig.3.
Center the Header Bracket on the vertical mark, no more than
6" (15cm) from the header wall. Mark and drill holes to fasten the
Header Bracket securely to a structural support.
