• Fasten the opener SECURELY to STRUCTURAL
SUPPORT of the garage to prevent falling.

Hanging Brackets
Use lag screws to attach angle
iron to the structural supports
before installing the garage
door opener onto a finished
ceiling. Measure the distance
from each side of the power
head to the angel iron.
Cut both hanging brackets to
appropriate length. Attach the
end of each hanging bracket
to the angle iron with 5/16" x
1" bolts and flange nuts.
Attach power head to hanging
brackets with 5/16" x 1" bolts and
flange nuts. Place level on rail; opener
should be level. Remove 2x4 and
manually close the door. If the door
hits the rail, either raise the head onto
the hanging brackets or if necessary
raise the header bracket.
Three most common installation options. Determine the mounting
option that works best for you.
*A 2x4 is ideal for setting the distance between the rail and the door at the highest point of door travel.
