"PIAA Si-Tech Silicone Flat Wiper Blade, 21"" (525mm) Brand New Includes 1 Year Warranty, The PIAA 97053 Flat Wiper Blade is an all-season, durable wiper blade that incorporates PIAA's patented silicone rubber
The key feature to its performance is its frameless design that creates more pressure points across the entire length of the blade for streak-free wiping and greatly reduced ice and snow build-up. The wiper design and blade compound ensure even greater visibility by coating the windshield with silicone to promote continuous water beading in inclement weather. The silicone coating also reduces drag and eliminates annoying and inefficient chattering and squeaking, regardless of the shape of the windshield, to provide greater comfort for both driver and passenger. 97053 Features: Blade Length: 21 Inch, Blade Pattern: Frame-less Silicone"
