Cast Iron Round Offset Rainwater Downpipe - Black (36 Sizes)

This Cast Iron Round Offset Rainwater Downpipe in Black is a traditional offset fitting designed to connect the gutter outlet to the vertical downpipe where the pipe run needs to clear a projection in the wall. Offsets are commonly used to bridge soffits, cornices, mouldings or other architectural features while maintaining a clean, continuous downpipe line.

Available in 36 different projection‑and‑width combinations, this offset pipe provides exceptional flexibility for both new installations and restoration work. Its authentic cast iron construction makes it ideal for Victorian, Georgian and Edwardian properties, as well as listed buildings where traditional materials are required.

The durable black finish blends seamlessly with classic cast iron guttering systems and offers long‑lasting protection against the elements. Cast iron is renowned for its strength, longevity and heritage appearance — many original Victorian installations still function today due to the material’s durability.

This offset pipe is suitable for use with round cast iron downpipes and is compatible with other fittings in the same range.
