Angled Water Blocking Strip for Sliding Windows

Protect your home from rainwater leaks, drafts, and mold with this angled water blocking strip designed for sliding windows and balcony frames. Its 135° design creates a smart downward slope that blocks incoming rain while guiding water away from window gaps. This keeps your window sill dry, prevents water accumulation, and reduces the risk of moisture-related damage.

Made from durable rubber with strong adhesion, the strip installs easily and stays firmly in place without peeling. Perfect for rainy seasons and homes exposed to strong winds, it enhances insulation while creating a clean, sealed barrier against the elements.
