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 drop end outlet provides a downpipe connection at the end of a G46 gutter run, used where the run terminates and drainage drops to a downpipe from the end section rather than from a central nozzle outlet. The G46 moulded profile is maintained at the terminal point, completing the installation consistently on the large Victorian and Edwardian properties where this pattern is standard.
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 drop end outlet is not interchangeable with common ogee fittings.
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.
Compatibility: G46 moulded cast iron gutter 125mm and 150mm only. 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.
The H542A measures 240mm wide x 240mm deep x 290mm high, making it well suited to a compact square profile suited to smaller Georgian and Victorian properties, extensions and outbuildings.
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.
