carton.
• Step 1, page 12 - Look at the wall or ceiling above
the garage door. The header bracket
must
be
securely fastened to structural supports.
• Step 5, page 17 - 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 21 - Depending
upon garage construction, wood blocks may need

provided.
• Step 11, page 24 - 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

• Align the 4 T-rail sections on a flat surface
exactly as shown. Center sections are
interchangeable. Front and back sections are
also interchangeable for ease of assembly.
• Insert the carriage bolts so the square bolt
necks seat in the square holes in the T-rail
sections and pass through the round holes in
the rail braces. Assemble lock nuts, ensure
alignment and tighten.
If T-rail is not assembled
exactly as shown, trolley
will not travel smoothly
along length of rail or it
will hit against nuts.

Assembly Step 3
Faster the T-rail to the Opener
• Place the opener on packing material to protect
the cover. For convenience, put a support under
the belt pulley bracket.
• Remove the (2) 5/16"-18x1/2" washered screws
mounted in the top of the opener.
• Align the holes in the back section of the T-rail with
the holes in the opener.
• Fasten the rail with the (2) washered screws
previously removed. Tighten securely.
Remember to use only these screws!

• Insert a 5/16"-18x7/8" hex screw into the trolley
stop hole in the T-rail as shown. Tighten securely
with a 5/16" lock washer and nut. This screw limits
trolley travel in the UP direction.
