The Amerimax gutter and downspout system features a black baked-on factory finish paint and durable aluminum construction. Our gutter systems will help control roof runoff and help prevent erosion. The decorative downspout band fits 2 in. x 3 in. aluminum downspouts and can be attached with screws or nails (not included). To install, use 2 downspout bands for each 10 ft. of the downspout and secure them to the wall.
