Assembly Step 1
Assemble the T-rail & Attach 
the Cable Pulley Bracket
• Align the 3 T-rail sections on a flat surface exactly
as shown. The end sections are identical. Make
sure the "arrow label" on the center section is
pointing toward the door.
• Insert the carriage bolts so the square bolt necks
seat in the square holes in the T-rail end sections
and pass through the round holes in T-rail center
section. Assemble lock nuts, ensure alignment and
tighten.

Make sure bolt necks are
seated in the square
holes and rails are
aligned before you
tighten lock nuts. (See
right and wrong views).
Improper assembly can
cause jerky trolley
operation, noise and/or
nuisance door reversals.
To avoid installation difficulties, do not run the garage door opener until instructed to do so.
