The alca® rear window wiper for vehicles with traditional wiper arm designs offers outstanding wiping performance and durability. Thanks to the stainless steel spring, even pressure is applied to the windshield, while the corrosion-resistant steel frame ensures a long service life. The wiper rubber has been tested by the Detroit Testing Laboratory, Inc. U.S.A. as permanently streak-free and is even more flexible and durable thanks to a nano-coating.
