Tired of keeping your speeds down when your wiper blades lift clear of the windshield on windy days? Air speeds over your windshield can be double the speed your speedometer shows, thanks to strong headwinds and the venturi effect that accelerates air as it comes over your hood. Flying wiper blades don’t wipe clean, so you need a blade that stays put.
- VorTec™ airfoil converts wind force for maximum windshield contact
- HighGlide™ treated rubber element for a smoother, quieter wipe
- Robust superstructure for durable all-weather performance
- SWIFT® Easy Connection Technology
Adding spring pressure to keep wiper blades in contact with the glass will simply overwork the wiper motor. Trico® Force™ is a highly-engineered beam blade with a patented swept-wing spoiler that slices through wind speeds in excess of 135 MPH (220 KPH) caused by cross winds, buffeting truck winds and general traffic turbulence. These wipers were developed in a wind tunnel/test track environment to assure adequate wiping at all vehicle speeds. High-speed wipe quality, a government and customer requirement, is measured up to the speed at which the vehicle is moving when the blade starts to lift. At this vehicle speed, wiping performance is severely affected. Testing this quality allows Trico® to engineer wiper blades that stay in contact with the windshield, even at higher speeds. The VorTec airfoil actually increases downforce as air speeds climb, while Trico’s HighGlide treated rubber glides more easily over the glass, keeping noise down.
Wiper blades have a tough day, even when it’s not raining. They sit on a hot windshield, out in the sun with its degrading UV radiation. They have to wipe off not only water, but also road grit, corrosive washer fluid and salt water from road salt. While the natural rubber from which blades are made provides the most flexible and resilient edge for wiping across glass, it eventually dries out and deteriorates. The rubber can become warped by heat or made brittle by cold. Modern windshields are curved, forcing the blade arm to articulate every swipe. A worn-out blade not only loses its sharp, rain-squeegeeing edge, it gets hard and won’t sweep the glass properly. Conventional blades have multiple joints between the superstructure and the wiping element that can corrode and freeze, further restricting mobility, and leaving you with streaks.
The most sure-fire cure is a blade replacement, and it’s the simplest one, too. Trico® blades are easy to install and fit your arms in exactly the same fashion as the OEM blades.
A collision on a rainy night in 1917 between a National Roadster and a bicycle (which fortunately didn’t injure either the cyclist or the Roadster) spawned an industry. Soon, the Tri-Continental Corporation introduced the first commercial windshield wiper. TRICO®, now a subsidiary of cooling system giant Stant, is one of the world’s leading manufacturers of windshield wiper blades, wiper systems and refills, with a large portion of both the aftermarket and OEM business..
