Wiper Blade Set Bosch Twin 420

Description

Bosch Twin 420 – frame set of wipers, 425 mm and 425 mm for streak-free performance.
Tackle every season head-on—the 420 dual windshield wipers incorporates all-weather construction, delivering flawless visibility in any condition.

The replacement blade boasts a robust metal frame with flexible rocker arms, designed to ensure optimal windshield contact on complex windshield shapes. The natural rubber wiping edge is firmly anchored in a U-channel, delivering a streak-free clean across the arc. Refill-compatible design and wide model coverage make it a budget-friendly solution for classic cars. It boasts 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 guarantees dependable performance, clear visibility and lasting value at an affordable price.
