Rubber Material: The window rain guards are made of rubber, which is cold-resistant, heat-resistant, UV-resistant, and anti-aging, ensuring a long service life and protecting window frames from rain damage. Easy to Use: The self-adhesive rain guards come with adhesive backing; easy peel off the backing and stick them on. Installation on doors, windows, and cars takes only seconds and requires no drilling. 135° Angled Edge + Deflector: The angled edge of the window sill rain guard deflects water away from gaps, while the deflector blocks wind-drivens backflow; providing double protection for sliding/casement windows. Leak-Proof Design: The waterproof window seals are developed for waterproofing, forming a physical barrier to keep window frames dry. Effectively prevents leaks during rain and protects walls from moisture erosion and peeling. Versatile Applications: The self-adhesive rubber rain guards are designed for gaps on the outer edge of windows, effectively preventing rainwater seepage during typhoons or heavy rain. Also suitable for areas prone to water seepage, such as the top of car doors and sliding window tracks.
