Assembly Step 1
Assemble the T-rail &
Attach the Belt Pulley Bracket
• Place the 3 T-rail sections on a flat surface for
assembly. 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.
