The Frost King DE300 Downspout Extender is designed to direct water away from your foundation. This extender fits all standard downspouts and provides three times the reach of standard extensions, allowing you to move water far from your home’s base during rainfall.
This manual downspout extender unrolls automatically when it rains and rolls back up manually when the weather clears, making it suitable for both seasonal and permanent use. The flexible construction allows you to cut it to any desired length using household scissors, adapting it to your specific needs. Installation requires no tools—simply slide the extender over your existing downspout and secure it with the included zip ties.
