To connect single-panel doors:
 Lower the garage door completely.
 Pull the emergency release rope down and slide outer
trolley toward the garage door.
 Place the curved and straight arms together and align
the holes.
 Choose two sets of aligned holes and install bolts and
nuts. Tighten bolts and nuts with a 1/2 in. socket.
NOTE: For better rigidity, install fasteners in holes that
are as far apart as possible.
 Secure straight door arm to the door bracket using small
clevis pin and hitch pin.
 Secure curved door arm to the rear of the outer trolley
using medium clevis pin and hitch pin.

WARNING:
DO NOT operate the garage door opener unless the
safety sensors are installed and working correctly. Failure
to properly install and ensure that the safety sensors are
working correctly can result in death or serious personal
injury.
WARNING:
The top of the sensor should be between four and six
inches above the floor. This will ensure that the door
reverses should a child, pet, or small object move
beneath the door as it lowers. Improper placement of
the safety sensors can result in death or serious personal
injury.
WARNING:
The effectiveness of the safety sensors included in this
system directly relates to the placement and installation
of the sensors. Incorrect placement or installation could
prevent the sensors from working as intended and result
in death or serious personal injury.
 Assemble the safety sensors by inserting the sensor stud
through the long slot in the bracket and securing with a
wing nut.
 Lower the garage door completely.
 Position both sensors on either side of the interior of the
garage door and point the lenses toward each other. The
arrow should be facing up.
