Description
The Denso Flat DF-409 set of wipers includes blades of 500 + 350 mm and features a frameless assembly.
Elevate exceptional visibility year-round with the DF409 dual windshield wipers — built to conquer rainstorms, icy sleet, snow flurries, and scorching heat with precision.
This Denso (Japan) DF409 set of wiper blades showcases an advanced asymmetric deflector, engineered for superior visibility in challenging environments.
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 gusty conditions. The result is reduced lift and chatter even in strong crosswinds.
Ideal for highway commuters, it enhances stability for lasting clarity.
Frameless windshield wiper blade delivers a sleek beam profile, precision-engineered to maintain constant glass contact across multi-radius glass. A resilient metal spine pairs with a premium silicone edge, ensuring a crystal-clear pass. Its low-drag aero spoiler cuts lift at highway speed, while smart-fit mounting heads suits most makes and models 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 – take your drive to the next level now.
