1. Turn the opened rail carton upside down and empty
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.
To prevent INJURYfrom pinching, keep hands and
fingers away from the joints while assembling the rail.
