Install inner locks and decorate them according to your preference.

If the sliding isn’t smooth enough. Recheck the rollers. Their role is to ensure the door slides smoothly

The height depends on the casing and header. It’s recommended that the door height is ½ inches larger. Once hung, have the door ½ off the floor. Making it to a total of 1 inch above the floor. The central rail should be 2inches above the door, cumulatively that will be 3inches above the opening.
