Figures 2, 3 and 4 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 17, or on the
garage

Figures 5 and 6 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.
