This 650 and 475 mm Bosch Aerotwin eA309S wiper blade set is built with a frameless assembly.
Frameless wiper blade unleashes a modern tensioned beam, precision-engineered to maintain constant glass contact across today’s sculpted windshields. A resilient metal spine pairs with a premium silicone edge, producing a whisper-quiet glide. Its wind-cheating contour boosts high-speed stability, while tool-free quick-click mount suits 95% of vehicles for hassle-free fitting. The frameless build shrugs off snow and ice, eliminates corrosion points, and hugs modern glass shapes for superior visibility. Drawbacks: higher upfront cost, refill inserts are non-serviceable, plastic adapters may embrittle in severe cold, and clamping force declines slightly on very flat windshields. Rinse with pH-neutral soap every three months and replace every 12–24 months (6–12 months in extreme climates). Go beam, drive clear – shop today.
