Product Description

The must-have add-on: this kit turns your gutter downspout into a free water supply, filling your rain barrel automatically every time it rains.
The Graf Universal Rain Barrel Downspout Connection Kit connects a closed rain barrel or tank to your downspout. A collector fits into the downspout and sends water through a 16" hose into the side of your barrel. When the barrel is full, extra water keeps flowing down the downspout, so there is no overflow mess. It comes in two versions: Rectangular for standard 3" x 4" or 4" x 5" downspouts, and Round for 4" to 5" downspouts. All parts are included, even the drill bit. Made in Germany by Graf.
๐ง Did you know? A 1,000 sq ft roof sheds about 600 gallons in a 1-inch rain. Without a downspout kit, almost all of that runs off into the street.
