Assemble the Rail

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

1.Open the rail carton and remove the contents onto a level work surface. Keep it clean and free of debris while you are working.

2.Identify the rail sections and orient the sections on a flat surface as shown. The back rail has a black gear on one end. The header rail has a black plastic rack inside the rail on the screw. The remaining section is the center rail.

NOTE: Use caution when handling the center rail section. The screw can slip out if the section is tipped up too far.

CAUTION

To prevent INJURY from pinching, keep hands and fingers away from the joints while assembling the rail.
