The Amerimax K-style gutter system is crafted from the highest quality aluminum and includes everything you need to protect your home from damaging roof water runoff. The Amerimax 3 in. x 4 in. brown downspout extension is used to bridge the gap between the overhang and the wall or whenever a short piece of downspout is needed to keep basements and foundations dry. Manufactured from rust-free aluminum with a baked-on brown finish for low maintenance. This piece can also be used at the bottom of the downspout to get the roof runoff away from the foundation. It is ideal for repair, replacement and add on to existing gutter systems.
