The Bosch Aerotwin blade features a unique bracketless design, a patented Quick-Clip connector system, and integrated aerodynamic wind spoiler. The enclosed steel tension springs greatly reduce the amount of exposed steel brackets and joints, providing improved resistance for perfect driving visibility, even in the worst weather conditions.
The integrated spoiler encloses the dual precision-tensioned steel springs. This combination of the bracketless design, internal tension springs and wind spoiler allows the blade to hug the windshield and wipe smoothly, evenly and quietly for a perfect wipe every time.
