This Floplast Anthracite Grey Square 112.5° Offset Downpipe Bend is commonly used to form a swan neck, which is the term given for two offset bends used together with a small piece of pipe in between. This allows the downpipe to drop from the fascia and return to the wall below the soffit. It is important never to use sealant or solvent weld when making a swan neck, as you may need to dissemble the fitting for cleaning at some point.
