Funnel size is based on bottom of gutter profile width. Still unsure? See our FAQ.

Traditional downspout outlets are small and easily clogged with debris, leading to drainage problems. The Fast-Flow Funnel is designed to boost water flow and reduce clogging at gutter downspouts. Fast-Flow Funnels enlarges the outlet, allowing for faster and more efficient water flow, preventing blockages. Made from durable aluminum, it won’t rust or corrode, ensuring long-lasting performance. For the best aesthetic match, we recommend colour matching the funnel to the colour of your gutters. Additionally, for added protection—especially if you have a buried gutter drainage system—pairing the Fast-Flow Funnel with our Leaf Grabber will help keep your entire gutter system clear and functioning smoothly.

Designed for 5" gutters. Made of aluminum. Available in 20 different colours to match your home's exterior aesthetic (additional colours may be available on request).
