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.
- Contact a qualified garage door service technician if your door binds, sticks or is unbalanced.
An unbalanced door might not reverse when required.
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).
1. Wall-mounting
a. Place the Header Bracket on the vertical centerline in direction shown.
b. 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.
2. Alternative Ceiling-mounting
a. Ceiling-mounting is suggested ONLY when clearance is minimal.
b. Extend the vertical centerline onto the ceiling. 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.
