The Square Pipe Side Offset provides a lateral offset for a cast iron square downpipe run, moving the pipe sideways across the wall face whilst maintaining the vertical run. Used where the pipe must clear an obstruction, step around a return wall, or align with a different point on the elevation below. The square section is maintained through the offset, preserving the geometric character of the pipe system.
Available in three sizes: 75×75mm (3″×3″), 100×100mm (4″×4″), and 125×125mm (5″×5″). Supplied in primed or factory black finish. Manufactured in cast iron to BS 460:2002. For specification support, call 0333 987 4452.

The Calnethorpe is designed for formal classical and Georgian elevations where scale and material authenticity matter — large townhouses, country houses, manor houses, and institutional buildings. It is also widely specified for new-build heritage projects where cast iron rainwater goods are required to conservation standard.
Our cast iron hopper heads are available in a standard primed and black-painted finish, ready for on-site topcoats. Heritage colour finishes and factory-applied linseed oil paint are available on request. Linseed oil paint is a vapour-permeable, period-appropriate finish particularly well suited to listed buildings and conservation area properties.
Please call 0333 987 4452 or use the contact form with the size, quantity and connection details, and we'll provide a quotation.
Yes. Cast iron rainwater goods are widely accepted by conservation officers and historic environment bodies as the appropriate material for listed buildings. Tuscan Foundry's hopper heads are manufactured in solid cast iron to BS 460 specification and are suitable for all listed building grades. A linseed oil paint finish is also available, which is particularly appropriate for conservation projects.
The Polished Brass finish suits buildings where brass metalwork was standard — formal Victorian terrace housing, civic and institutional buildings, and high-quality estate architecture. It is appropriate on listed buildings and conservation properties where the wider ironmongery specification is in brass and a matching material is required.
The handle is compatible with Lumen Rooflights and most pole-operated rooflight and skylight systems. If you are unsure whether it suits your specific rooflight, call us on 0333 987 4452 and we can advise.
Bespoke and copy cast iron rainwater goods typically have a lead time of 12 to 14 weeks from order confirmation. This covers pattern-making, casting, finishing, and quality inspection. Stock items are typically despatched within 5 to 7 working days, and non-stock standard profiles within 7 to 10 working days. We always recommend confirming lead times at enquiry stage so your project programme is not affected.
Yes. Cast iron hopper heads are the historically correct choice for listed and period buildings, and a like-for-like cast iron replacement is generally accepted without objection by conservation officers. We manufacture to BS 460 for genuine heritage character and durability.
Hopper heads are supplied in red oxide primer ready for on-site painting, or pre-finished in black. A full range of Heritage Colours in traditional linseed oil paint is also available on request — please contact us for the swatch chart.
Yes. Cast iron is the material required by most conservation officers and listed building consents for the replacement or replication of traditional rainwater goods. Our hopper heads are produced in solid cast iron and we can assist with specification notes or material statements for planning purposes if required.
