Aluminium 112.5 degree downpipe bends are used to create a bend in the run of an aluminium downpipe or more commonly, create a swan neck. A swan neck is created to take the downpipe from the running outlet, around the fascia and soffit and back against the wall. This section is made by getting two downpipe bends, cutting a small piece of downpipe and fitting the small piece of pipe in between the bends.For more information about how to install our swaged downpipe system, please take a look at our downpipe installation guide.
