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.

as shown. Center sections are interchangeable.

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.
• Position the cable pulley bracket on the front end
of the T-rail as shown. Fasten securely with the
