Our cast iron rectangular pipe offset is used to join the pipe to the gutter outlet when then the pipe is not aligned directly below. Our swan neck offsets are available in 10 sizes ranging from 3″ to 24″. With the rectangular pipe, your offset is either front or side-facing. This product selection is for side facing and projections between 305mm (12″) and 610mm (24″).
Our cast iron rectangular rainwater offset (also known as swan necks) is available in 10 sizes ranging from 56mm (2.25″) to 610mm (24″). The size (projection) is taken from centre to centre in a straight line and relates to how far you have to span between the outlet and pipe. Our standard cast iron rectangular front and side-facing offsets are all produced at an angle of 112.5 degrees.
Our cast iron rectangular rainwater pipe is available in four diameters which are 4"x3, 5"x2.75", 5"x4" and 6"x4" and this selection is for side-facing offsets ranging from 12" to 24" projection.
The rectangular rainwater pipe design is used where it is necessary to remove large volumes of water from the roof or where a statement architectural feature is required. Due to the large size of these cast iron downpipes, they are better suited to our wider cast iron gutter profiles. The rectangular cast rainwater pipes are ideal for heritage or listed properties and will offer great benefits to more contemporary projects. The rectangular branch is a plain version and is held in position by the guttering and pipes.

Our standard range of cast iron rainwater pipe profiles includes round, square and rectangular. In addition to these cast iron profiles, our range can be complemented with unique bespoke products which can be manufactured to meet your size and design requirements.
Some of our cast iron products such as the cast iron square rainwater pipes are made to order. They are available within the Metal & Glass cast iron range but need to be cast or fabricated with timescales being slightly longer than our off-the-shelf stock products. They can be ordered securely via our website in exactly the same way as ex-stock products. These cast iron made-to-order items are available in both the grey primer and gloss black painted finish.
We can also offer bespoke hoppers to match original designs as well as adapt existing cast iron hoppers by changing outlet sizes and positions.
