Most of the time when you seek out a door, you will see many of the same things. Not necessarily that all doors are the same, but rather you will see many of the same styles.

The horizontal doors used on closet sliding doors move along a track mounted overhead and a floor guide for stability. To manage the smooth movement they‘ll have cushions and buffers on the ends to prevent damaging adjacent construction to ensure a smooth gliding motion when operated. Closet sliding doors of the vertical variety are seated in a groove, much like dresser drawers to ensure they glide in one direction.
