Cast Iron Round Downpipe Branch – Primed Finish (Multiple Angles & Sizes)

This Cast Iron Round Downpipe Branch in Primed Finish is a traditional rainwater fitting designed to join a secondary downpipe into the main vertical pipe. Branches are commonly used where additional roof areas — such as porches, bay windows, dormers or extensions — need to feed into the primary drainage system. This makes them an essential component for both new guttering installations and period property restoration.

Supplied in a durable primed coating ready for painting, this branch allows you to finish the pipework in any colour while maintaining the authentic appearance of cast iron. Once painted, the fitting blends seamlessly with heritage guttering systems and provides long‑lasting protection against the elements.

The branch is available in multiple angles and diameters, allowing you to select the exact configuration required for your building. Typical angles include 92.5°, 112.5° and 135°, ensuring proper alignment between the incoming pipe and the main downpipe. These angles are standard across cast iron rainwater systems and are widely used in Victorian, Georgian and Edwardian architecture.

Cast iron remains the material of choice for conservation projects due to its strength, longevity and unmistakable period character. This primed branch is fully compatible with traditional round cast iron downpipes and other fittings in the same range.

Ideal for listed buildings, heritage restorations and high‑quality new builds, this branch provides a robust, visually authentic and architecturally correct solution for traditional rainwater systems.
