This product is for use on sectional garage
doors only.
Serious personal injury could
result from the use of this product on onepiece garage doors.
Before you begin, complete the following test to make sure your door is balanced and is not sticking or
binding. Identify the type and height of your door, any special conditions that exist, and any additional
materials that may be required by referring to the lists on page 4.
• Lift the door about halfway as shown. Release the
door. It should stay in place, supported entirely by
its springs.
• Raise and lower the door to see if there is any
binding or sticking.
An unbalanced garage door might not reverse
when required and someone under the door
could be seriously injured or killed.
If your garage door binds, sticks or is out of
balance, call for professional garage door
service.
Garage doors, door springs, cables,
pulleys, brackets and their hardware, are under
extreme tension and can cause serious injury or
death.
Do not try to loosen, move or adjust them
yourself!

Safety Reversing Sensor
Based on your particular requirements, there are
several installation steps which might call for
materials and/or hardware not included in the
carton.
• Step 1, page 8 - Look at the wall or ceiling above
the garage door. The header bracket
must
be
securely fastened to structural supports.
• Step 5, page 12 - Do you have a finished ceiling in
your garage? If so, a support bracket and
additional fastening hardware may be required.
• Safety reversing sensor, page 16 - Depending
upon garage construction, wood blocks may need
to be fastened to mounting locations before
sensors are installed.
• Step 10, page 17 - Alternate floor mounting of the
safety reversing sensor will require hardware not
provided.
• Step 11, page 19 - Do you have a steel, aluminum,
fiberglass or glass panel door? If so, horizontal
and vertical reinforcement is required.
• Look at the garage door where it meets the floor. It
must close on the floor all the way across. Otherwise, the safety reverse system may not work
properly. See page 23. Floor or door should be
repaired.
• If your door is more than 7 feet high, see longer
rails available on page 30.

Outer Nut
• Spin the inner nut and lock washer down the
threaded shaft, away from the trolley.
• To tighten the chain, turn outer nut in the direction
shown. As you turn the nut, keep the chain
from twisting.
• When the chain is approximately 1/2" above the
base of the rail at its midpoint, re-tighten the inner
nut to secure the adjustment.
Sprocket noise can result if chain is either too
loose or too tight.
When installation is complete, you may notice some
chain droop with the door closed. This is normal. If
the chain returns to the position shown when the
door is open,
do not re-adjust the chain.
