Assemble the Rail

To avoid installation difficulties, do not run the garage door opener until instructed to do so.

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 joint.

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.
