HEADER AND DOOR MOUNTING BRACKETS:
WARNING
Header bracket must be fastened to garage
framing.
Do NOT
fasten to drywall, particle
board, plaster or other such materials.
1. Finding header bracket mounting location.
• Close garage door.
– Use a pencil and level.
a) Mark center of garage door (
one-half
overall width
) on the wall with 6" vertical
line at top edge of door.
b) Continue this line on wall above door for
about 12"
(Fig. 2-1, a).
• Raise garage door until
top edge
of door
reaches its maximum height
(Fig. 2-2).
• With door at highest point.
– Measure height from top edge of door to
floor
(Fig. 2-2).
• Close door again.
• Mark height measurement on wall above door
(Fig. 2-1, c).
– Make your mark across vertical line made
earlier.
• Add 2-1/2" to height mark just made on wall.
This is location for header bracket
(Fig. 2-1, d).
WARNING
Door springs are under high tension. If spring
or its shaft is in the way, measure 2-1/2" above
spring or shaft on the garage door centerline
and mark this height as your location for header
bracket.
Do NOT move door spring!
NOTE: If header bracket location needs to be above
header for garage door opening, you need to add
a "mounting surface." A 2" x 6" board securely
attached (board and fasteners not included) to
wall studs on either side of your mark is sufficient
(Fig. 2-3).
NOTE: For header bracket and bolts locate Bag 2
from Box 1.
