Install The Safety Reversing Sensor - Craftsman 139.53662SRT2 Owner's Manual

Installation Step 10
Install the Safety Reversing Sensor
Figures 2 and 3 show assembly of brackets and
"C" wrap based on the recommended installation of
the sensors as shown on page 21.
However, 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.
• Fasten the "C" wraps to the mounting brackets
having square holes, using the hardware shown
in Figure 2.
• Connect each assembly to a slotted bracket, using
the hardware shown in Figure 3.
Note the alignment of the 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 21 .)
• Attach bracket assemblies with 1/4"x1-1/2" lag
screws as shown in Figure 3.
• Adjust right and left side bracket assemblies to the
same distance out from the mounting surface.
Make sure all door hardware obstructions are
cleared. Tighten the nuts securely.
