65mm Cascade Cast Effect Square Downpipe

Brett Martin’s 65mm guttering downpipe has a distinct square profile, giving your installation a sleek, contemporary edge. This innovative cast iron effect downpipe is specifically compatible with 106mm Prostyle guttering and ensures seamless integration into your rainwater system.

Available in eight elegant colours, the square downpipe meets diverse design requirements. However, if you’re seeking an authentic heritage look for your Prostyle guttering system, consider the 68mm Round Downpipe for closer historical accuracy.
