The sole purpose of this product is to join up your gutter and downpipes when the gutter is sitting an unwanted distance away from the walls. This product is therefore designed as an extension to connect from the running outlet, back into the wall and around the soffit. In cases where your gutter and downpipe do not perfectly meet, it is sometimes necessary to fit a Zinc Gutta swan neck so your downpipes can sit slick to the wall. Installers can be confident that this product is easy to install and its hard wearing but lightweight nature can guarantee its reliability.
