The all-season wiper blades are flexible rubber strips with a flat, arc-shaped metal spring. Their design considers aerodynamic properties to avoid unnecessary noise and maintain high glass cleaning quality at increased speeds. The resilient guide rail makes the brushes suitable for all seasons and resistant to high and low temperatures. The brushes precisely follow the contours of the glass, adhere evenly and, thanks to the NANO-Graphite® liquid graphite coating, clean perfectly without streaks in both directions.
