The lift&slide rollers cover everything the market requires, handling from 200 kg to 400 kg either individually or in tandem. For heavy sash weights from 250 kg, the use of additional rollers is recommended. The spring system additionally handles 80 kg each.
A two-part (in total four wheeled) roller set ensures smooth and quiet running for each sash element. A brush is also positioned on each roller, which sweep dirt off the running rail with every sliding movement and support the clean, quiet rail guide.
