The Amerimax StealthFlow Low Profile Downspout Extension Kit is an innovative accessory that helps divert damaging rainwater away from your home and your foundation. The low profile design of the extension is designed for an unobtrusive look and can be covered with mulch, straw or stones for a subtle appearance, with no digging required. It is designed to work with both 2 in. x 3 in. and 3 in. x 4 in. downspout with a simple cut line to fit the larger downspout application.
