1. Turn the opened rail carton upside down, emptying its
contents onto a level work surface.
2. Unfold the rails, taking care to avoid kinking the screw
rod joints.
3. Rotate the rail sections so that the flat side is down and
the screw side is up for all three lengths. Keep it clean
and free of debris while you are working.
CAUTION: During assembly, avoid pulling the rail
section housing the trolley rack away from the screw
rod. The rack is factory set about 9" from the end of the
screw rod to the center of the rack.
If the plastic liner slides part way out during assembly,
simply push it back in.
To avoid installation difficulties, do not run the garage
door opener until instructed to do so.
