ASSEMBLY STEP 1
Assemble Rail and Attach the Cable Pulley Bracket
FOR SECTIONAL AND ONE-PIECE DOORS ONLY
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.
