ASSEMBLY STEP 1
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 three rail sections on a flat surface
exactly as shown. Front and back sections are
interchangeable for ease of assembly.
2. Insert the carriage bolts so the
square bolt necks seat in the square ,_L
holes in the rail sections and pass
through the round holes in the center
section rail. Make sure bolt necks
are seated in the square holes and
rails are aligned before you tighten
lock nuts. Improper assembly can
cause jerky trolley operation, noise
and/or nuisance door reversals.
3. 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.
4. Position the cable pulley bracket on the front end
of the rail as shown. Fasten securely with the
hardware shown.
NOTE: When tightening the bolts, be sure to keep
bracket parallel to the rail. Otherwise, the rail may
bow when the opener is operated.
