Types of folding door track systems

1) Bi-Fold / End Folding Sliding Doors (door fixed in corner of the panel)

Doors fold at the end of panels and lay flat when in the open position. This method uses the least amount of space to store the doors and only protrudes from one side of the track.


2) Harmonica / Centre Folding Sliding Doors (door fixed in middle of the panel)

Doors fold from centre of panels and lay flat when in the open position. This method requires that the first door panel is half the width of all of the subsequent doors. It utilises the space on both sides of the track so that the storage is not all to one side.
