The Anco Wiper Blade Insert is a perfect replacement for your worn-out stock. The product is equipped with Anco's DuraKlear all-natural rubber technology that allows a streak-free cleaning at every wiping. This keeps your windshield from incurring damages, allowing you to maintain its overall quality. Aside from providing an efficient clean, this wiper blade insert fits directly into your wiper blades.

Each Anco Wiper Blade Insert can be easily attached to the frame or plastic structure of your wiper for easy installation. Anco also made this product available in a variety of lengths with two series of wiper blade inserts.
