Attach the Belt Pulley Bracket
• Align the 4 T-rail sections on a flat surface
exactly as shown. Center sections are
interchangeable. Front and back sections are
also interchangeable for ease of assembly.
• Insert the carriage bolts so the square bolt
necks 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.
If T-rail is not assembled
exactly as shown, trolley

along length of rail or it
will hit against nuts.
