The 72-degree bends by Zinc Gutta are the perfect components to create a swan neck from your running outlet to your downpipe. 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. The bends are used to allow the rainwater to flow smoothly from your gutter into the downpipe to ensure optimum flow rate. Manufactured in robust zinc, 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.
