Wiper Blade Bosch Twin 420U

Description

The Bosch Twin 420U spans 425 mm and offers a frame configuration for optimal contact.
Bosch Twin 420U delivers universal, year-round durability—clearing away sleet, snow, and debris for a spotless windshield on every drive.

The windshield wiper delivers a sturdy steel skeleton with flexible rocker arms, crafted to provide precise downforce on complex windshield shapes. The synthetic EPDM wiping edge is firmly anchored in a metal groove, delivering a consistent sweep across the arc. User-friendly blade swaps and wide model coverage make it a budget-friendly solution for older models. It features a durable galvanized frame that resists corrosion and mechanical wear, a multi-pivot action that adapts to complex windshield curves and a simple rubber refill system that extends service life while reducing total cost of ownership. However, exposed hinges may freeze and clog with dirt during winter, at high speeds it can experience wind lift and increased noise, and natural rubber wears faster in sunlight whereas polymer composites command a higher price. Periodically clean and lubricate the hinges with a silicone spray every three to six months and replace the wiping edge every six to twelve months (or every four to six months in harsh climates). Perfect for mild weather, daily commuting and economical drivers, this blade ensures dependable performance, clear visibility and lasting value at an affordable price.
