First you will have to cut the rail:
Use a miter box that will hold the rail. Remember to protect the rail with tape because the filings created by cutting will scratch the paint. With a good hacksaw, cut your profile. As the surface of the sheet is folded in several directions, the saw tends to get stuck. It is imperative to saw pressing only very slightly.
For cutting the top rail, insert such a piece of polystyrene (diagram) between the cheeks for they do not vibrate during cutting. While one person holds the profile on the bench, the other makes the cut.
Starting sawing and to prevent the saw from sliding sideways and scratched the paint, keep your thumb firmly on the rail. The thumbnail will be placed vertically against the saw to be his guide. Secure the rail above the ceiling so that the doors are in the desired location.
Fitting the lower guide rail
If you align the bottom rail with the top rail by yourself ... your kitchen cabinet doors will not be vertical. Temporarily place a door in the top rail and a wheel in the lower rail. Check the verticality of the door with a level and mark the position of the bottom rail. Remove the door and secure the rail.
Finishes
Mount the door on the rail. Choose the position closed doors (eg door left front and the rear door on the right). Using a screwdriver, adjust the height of the rollers so that in the closed position the door edge is flushed against the wall.
