| Centre Stack | Side Stack | Remote Stack |
| A simple straight track. Each panel is suspended from a central trolley and typically hinged in pairs. Often closed by a jamb hung pass-door. | Single panels are suspended from 2 carriers at the top corners of each panel. Panels stack with one carrier remaining on the main track and the other in the side track. | Panels have omnidirectional carriers to negotiate X, L or T junctions and panels are stacked completely away from the main track, sometimes in a cupboard or recess. |
