(Receiving and Sending Eyes)
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.

square holes, using the hardware shown in 1.
Garage Wall Installation Procedure
