Here are the steps to install sliding closet doors:

1. Measure the Space: Start by getting the measurements of the finished opening of the closet. First, measure the top of the closet and mark it down.

2. Install the Tracks: The top track is usually the trickiest part to install. You will need to use a level to make sure that it is straight.

3. Install the Floor Guide: Sliding closet doors without a bottom track usually have a floor guide that you need to install. Only in the case of very light doors that you would have neither bottom tracks nor floor guides. To install the floor guide, mark the middle of the closet door on the floor and drill a hole into it.

4. Secure the Roller Brackets: The roller brackets are what hold the doors in place. You will need to screw them into place.

5. Install the Sliding Closet Doors: Once you have everything in place, you can install your sliding closet doors.

6. Make Necessary Adjustments: After installing your sliding closet doors, you may need to make some adjustments.

7. Install the Handles: Finally, you can install your handles.
