A two-part (in total four-wire) roller set is used for each sash unit. A brush is located on each roller. These brushes sweep the dirt from the roller track with every movement, thus permanently ensuring smooth running. Additional rollers are recommended for a sash weight above 250 kg. Thanks to their suspension system, they can handle an additional 80 kg sash weight each.
