More Details:

Bosch Type Iron Bone Wiper use a stainless steel backing to better contact the wiper blades and remain stable at high speeds, reducing bounce and noise on the windshield. Stainless steel backing resists aging and deterioration caused by factors such as UV rays, oxidation and chemical corrosion. The design of the stainless steel backing usually makes it easy to replace the wiper blade part. When the blade is worn or damaged, only the blade needs to be replaced instead of the entire wiper, which is more economical and convenient. The iron frame design of the wiper can provide a uniform wiping effect through the pressure distribution of the iron frame, making the wiping results more thorough and clear. The iron frame has high strength and resistance, can withstand long-term and high-speed driving, and has a longer service life. Bosch type iron frame wipers are produced in strict compliance with OEM standards to ensure that their quality is the same as original parts, providing car owners with the same matching and use experience as the original car.
