45 degree bends are used to change the path of a run of downpipe in a Lindab steel rainwater system. Two of them can also be used to create an offset or swan-neck in the downpipe by fitting a small piece of cut downpipe between them.One of the ends of the bend has a small label on it, and this is slightly smaller than the other end as it is designed to slot into the next downpipe fitting.
