Description
The Denso Flat DF439 comes as a frameless construction wiper blade set with 550 and 400 mm blades.
With its weatherproof construction, the set of wipers DF439 guarantees clear visibility from sub-zero temperatures to sweltering conditions.
The Denso (Japan) DF439 set of wipers offers an advanced asymmetric deflector, engineered for unmatched clarity in challenging environments.
An asymmetric spoiler is strategically positioned to channel airflow into enhanced blade pressure 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 a streak-free visibility even in demanding high-speed scenarios.
Ideal for highway commuters, it boosts wipe efficiency for lasting clarity.
Frameless wiper blade unleashes a modern tensioned beam, calibrated for constant glass contact across today’s sculpted windshields. A pre-curved spring-steel beam pairs with a premium silicone edge, producing a crystal-clear pass. Its wind-cheating contour boosts high-speed stability, while slide-in multi-adapter suits most makes and models 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 – buy today.
