The Bosch Micro Edge Excel wiper blade is a precision-cut rubber blade that's easy to install and is made from heavy-duty material that resists wear and tear, and provides a smooth glide. And now with an exclusive dual rubber compound housed in an aerodynamic steel frame, this blade cleans windshields better and lasts longer than ever before. Plus the DirectConnect mounting system makes for quick, easy installation. The result is less streaking and unmatched resistance to wear.
