Depending on the design of your system, installers will either need to fit a swan neck to the running outlet before it meets the downpipe, or the downpipe can be directly fixed on. This product boasts easy installation as all the running outlets can be push fitted into place, without the need for a sealant. Running outlets are one of the most crucial components to complete your drainage system. This is the tool that carries the rainwater away from the gutter and into your standard ogee downpipes.
