Description
Denso Flat DF-409 – frameless wiper blade set, 500 + 350 mm for maximum reach.
Master every season head-on—the Denso Flat DF-409 set of two all-weather wipers features weatherproof design, ensuring flawless visibility in any weather.
The Denso Flat DF-409 set of wiper blades features an asymmetric-style spoiler, crafted to ensure superior visibility in high-speed scenarios.
An asymmetric spoiler is strategically positioned to channel airflow into optimal contact force while reducing aerodynamic resistance, applying extra pressure to the wind-facing edge so the blade hugs the glass during fast-paced drives. The result is reduced lift and chatter even in strong crosswinds.
Ideal for highway commuters, it enhances stability for dependable performance.
Frameless replacement blade delivers a modern tensioned beam, purpose-built to hold even line pressure across today’s sculpted windshields. A pre-curved spring-steel beam pairs with a advanced synthetic-rubber edge, ensuring a whisper-quiet glide. Its wind-cheating contour cuts lift at highway speed, while tool-free quick-click mount suits 95% of vehicles for rapid installation. 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). Experience silent clarity – elevate now.
