Rain-X 18" Latitude Wiper Blade. It features a universal adaptor system that simplifies installation and eliminates the need for packaged adapters. The new water repellency application with Latitude water repellency ensures a smooth, clean, and chatter-free wipe. The contoured design applies even pressure along the entire blade, while the specially blended graphite coated rubber blade delivers the ultimate smooth, clean, chatter free wipe. The built in aerodynamic spoiler significantly reduces drag, noise and wind lift. It prevents ice and snow build up through the elimination of exposed metal components. It is for use on either originally installed standard or curved style wiper blades.
