What type of door has components that include rollers or glides, similar to those on sliding doors?

Folding doors, also known as bi-fold or accordion doors, utilize components like rollers or glides to facilitate their opening and closing mechanisms. These rollers allow the door panels to glide along a track, enabling them to fold and stack neatly to one side. This design is particularly advantageous in spaces where traditional doors would require more clearance or where maximizing open space is necessary.

In contrast, revolving doors operate by rotating around a central axis and typically do not utilize a gliding mechanism like those found in folding doors. Swinging doors are hinged on one side and swing open in a traditional manner, lacking the track-based movement seen in folding doors. Vertical doors, which might refer to garage doors or similar types, typically operate with a different mechanism entirely, often involving pulleys and springs rather than rollers or glides.

Therefore, the presence of rollers or glides as key components distinctly identifies folding doors as the correct choice in this context.
