Manufactured in robust stainless steel, it is recommended that installers use two bends and a small piece of downpipe to create the correct shape that ensures a smooth rainwater transition from gutter to drain. The Stainless Gutta 72-degree bends are the ideal component to form a swan neck from your running outlet to your downpipe. The bends are used to allow the rainwater to flow smoothly from your gutter into the downpipe to ensure optimum flow rate. By forming a swan neck from your running outlet, it allows you to position all pipes closely to the wall for a neat and modern finish.
