Figures 1, 2 and 3 show recommended assembly of
bracket(s) and "C" wrap based on the wall installation of
the sensors on each side of the garage door as shown on
page 12, or on the garage door tracks themselves. 

Figures 4 and 5 are variations which may fit your
installation requirements better. Make sure the wraps
and brackets are aligned so the sensors will face each
other across the garage door.

Garage Wall or Door Track Installation Procedure

• Fasten the "C" wraps to the mounting brackets having

square holes, using the hardware shown in 1.

Garage Wall Installation Procedure 

• Connect each assembly to a slotted bracket, using the

hardware shown in 2. Note alignment of  brackets for
left and right sides of the door.

• Finger tighten the lock nuts.
• Use bracket mounting holes as a template to locate and

drill (2) 3/16" diameter pilot holes on both sides of the
garage door, 4"-6" above the floor but not exceeding 6"
(see warning on page 12).

• Attach bracket assemblies with 1/4"x1-1/2" lag screws

as shown in 2.

• Adjust right and left side bracket assemblies to the same

distance out from mounting surface. Make sure all door
hardware obstructions are cleared. Tighten the nuts
securely.
