A genuine cast iron rainwater pattern the G46 or No.46 is available in two profile sizes. The profile is a larger version of the more traditional ogee (OG) curved pattern and offers increased capacity.
UK delivery from £30. Fittings are despatched boxed. See delivery rates.
The cast iron G46 moulded gutter stop end closes the open end of a G46 gutter run. The full moulded section is maintained through the stop end, completing the run neatly at a gable end, chimney return, or other point of termination on the large Victorian and Edwardian properties where the G46 is the standard profile.
Manufactured in solid cast iron to BS 460:2002. Available in both G46 profile sizes: 125mm (5″) and 150mm (6″). Supplied in primed or factory black finish. The G46 stop end is not interchangeable with common ogee fittings — always specify the correct G46 stop end to ensure profile match.
Specified on listed buildings and heritage restoration projects where the G46 moulded pattern is the historically correct profile. Accepted by conservation officers as the appropriate fitting for period rainwater work on substantial Victorian, Edwardian, and later period buildings.
Compatibility: G46 moulded cast iron gutter 125mm and 150mm only. For specification support, call 0333 987 4452.

Linseed oil paint is the most appropriate finish for cast iron guttering on listed and historic buildings. It is breathable, flexible, and penetrating — qualities that suit the movement characteristics of cast iron through seasonal temperature changes. Tuscan Foundry Products offers a curated range of heritage linseed oil colours. For modern applications, a high-quality exterior oil-based paint system over a metal primer is also acceptable.
We are able to place dates and initials and insignia onto most of our flat faced rainwater hopper heads.
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.
Our cast iron airbricks are available in a choice of finishes including primer and painted options. If you require a specific finish for a conservation project or to match existing ironwork, please call us on 0333 987 4452 to discuss.

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.
The Regent H1 is well suited to Victorian and Edwardian terraces, listed commercial buildings, civic and institutional properties, and ecclesiastical buildings where a traditional funnel-form hopper is architecturally appropriate. Its multi-faceted tapering body reads as period-accurate on Gothic and classical building types alike, and it is a commonly specified choice for conservation and listed building projects across the UK.
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.
BS 460:2002 is the British Standard governing cast iron rainwater goods — gutters, pipes, and fittings. It sets the dimensional tolerances, materials, and performance requirements a component must meet, so that joints seal, sections align, and the system performs as a whole rather than as isolated parts. All Tuscan Foundry Products components are manufactured to comply with BS 460:2002, which is worth citing directly in specification documents and listed building consent applications. The same manufacturing standard applies to bespoke and copy-cast work, even where the profile itself isn't from our standard range.
The School Board Airbrick suits Victorian and Edwardian institutional, civic, and residential buildings where the square-grid airbrick pattern was standard — including school buildings, civic halls, estate housing, terrace houses, and warehouses. It is also appropriate on listed buildings and conservation area properties as a like-for-like replacement for worn square-grid cast iron vents.
