Our take on the Amerimax Flex-a-Spout Downspout Extension, Stone Roof Gutter Accessories

The Amerimax Flex-a-Spout is a corrugated downspout extension that bends around corners, shrubs and landscaping and holds the shape you set. It fits both 2x3 and 3x4 downspouts and stretches to about 55 inches, so one part covers most residential gutter setups. Compared with rigid metal or vinyl extensions, it is easier to route and less likely to be knocked loose, but it is a flexible plastic piece rather than a buried drainage system. It suits homeowners redirecting roof runoff away from foundations and beds.

Questions and answers

Will it fit my downspout?
It is designed for both 2x3 and 3x4 inch downspouts. Check your outlet size and fasten it if the fit feels loose.
How far does it extend?
It stretches to about 55 inches. You can shorten the run by leaving some of the corrugation compressed.
Can it be buried underground?
No. It is a surface extension for directing runoff away from the house, not a buried drain line.
Does it stay in the shape I bend it to?
Yes, the corrugated body holds its position around corners. Long unsupported runs may still sag over time.
Is it better than a rigid extension?
It is easier to route around obstacles and less likely to be knocked loose. Rigid metal or vinyl may last longer in open, straight runs.
