ECOGARD LOGIC SERIES has a premium beam blade design to perform better on todays modern contoured windshields by providing uniform pressure where the rubber meets the glass. ECOGARD SUPERIOR BEAM WIPER BLADES ARE RATED FOR ALL-WEATHER PERFORMANCE and help reduce hazardous driving by delivering a consistent streak-free wipe across the entire sweep of the wiper arm, even in the heaviest of rains. ECOGARDS AERODYNAMIC DESIGN offers a sleek, modern appearance while keeping the wiper blade pressed against the windshield during high speeds to avoid wind lift, chatter and streaking.
