Are three-stage wiper blades frameless?

[Hector]

Three-stage wiper blades belong to the frameless type. They feature a three-section plastic sleeve covering the bridge frame, with a curvature design that ensures better fit. This addresses the shortcomings of ordinary frameless wipers, such as unclear wiping at the joints on some vehicles and the inability of the ends to adhere properly to the glass. Below are related details: 1. Wiper operation modes: Wipers generally have three operation modes: intermittent wiping, which occurs approximately every four seconds, suitable for light drizzles; low-speed wiping, used for moderate rain or snow; and high-speed wiping, employed during heavy rain or snow. Frameless wiper blades use high-quality natural rubber for the blades, ensuring cleaner wiping and a longer lifespan. 2. Traditional wipers: Traditional wipers have multiple pressure points, whereas frameless wipers utilize an integrated steel strip for more even pressure distribution. When replacing frameless wipers on a car, there is no need to replace the wiper arm; however, replacing traditional wipers requires changing both the wiper blade and the wiper arm together.
