ASSEMBLY STEP 1
For Sectional and
One-Piece Doors ONLY
Assemble the Rail and
Attach the Cable Pulley Bracket
To avoid installation difficulties, do not run the
garage door opener until instructed to do so.
1.
Align the four rail sections on a flat
surface exactly as shown. Center
sections are interchangeable. Front
and back sections are also
interchangeable for ease of assembly.
2. Insert the carriage bolts so the square
bolt necks seat in the square holes in
the rail sections and pass through the
round holes in the rail braces.
Assemble lock nuts, ensure alignment
and tighten.
NOTE:
If rail is not assembled
exactly as shown, trolley will not travel smoothly
along length of rail or it will hit against nuts.
3. Position the cable pulley bracket on the front end
of the rail as shown. Fasten securely with the
hardware provided.
NOTE:
When tightening the bolts be sure to keep
bracket parallel to the rail. Otherwise, the rail may
bow when the opener is operated.
