The A&E Systems WeatherPro power awning provides superior perfomance and great looks. To prevent damage to the awning or coach, a wind sensor closes the awning automatically when it detects high, sustained winds. The exclusive Knee Action Design™ allows the awning to automatically flex in moderate wind, avoiding nuisance retractions. In the event of rain, a unique spring arm mechanism automatically flexes to release accumulating water away from the door. This brings a clean, level, maintenance-free appearance to your RV.
