Choosing the doors mostly depends on your tastes. They can be made of glass, mirror or wood. For better installation and efficiency the door shouldn’t be thicker than 3/4 of an inch and 1 3/8 inches. You can even transform an existing door into a sliding one, as long as you have the right tools and hardware.

Installing overhead track

The first thing you need to to for the installation of the sliding door is to properly fit the overhead track. You should fix the track against the door opening’s head jamb. To level the track, use some shims.

Door rollers

The door rollers need to be attached to the top and door. They will fit within the closet’s overhead track. They are also adjustable just to make sure that the door is capable of plumb hanging.

Installing tracks

To make sure that the doors are kept in line, you need to install some guides on the bottom of the door. The top and bottom tracks need to line up completely if you want the door to operate as it should be.

Hanging doors

You will need to push the door up into the tracks at a certain angle to line them up properly with the wheels from the tracks. The door needs to slide freely.

Adjust tracking guides

After you slide the door into the top tracks, you need to adjust the guides from the bottom of the door. The tracks will keep the door in place and keep it from swinging inward or outward.


Next thing you need to do is install the decorative trim. Then you should cover any hardware, as well as making sure that the door is aligned.
