The RB500G46 is a top rafter rise and fall bracket for the G46 moulded cast iron gutter. Where open eaves construction or the absence of a fascia board requires fixing to the top surface of a rafter, the RB500G46 provides a secure, adjustable support that allows precise fall setting across the gutter run. The bracket cup is dimensioned specifically for the G46 moulded section — the larger Victorian and Edwardian ogee profile — ensuring a correctly seated fit.
Available in both G46 profile sizes: 125mm (5″) and 150mm (6″). Zinc-plated steel finish for outdoor corrosion resistance. The threaded rise and fall cup eliminates shimming and allows accurate gradient control on long runs or complex roof lines, which is particularly important on the large Victorian and Edwardian buildings where the G46 profile is commonly found.
Specified on listed buildings and heritage restoration projects where the G46 moulded pattern is the historically correct profile. The RB500G46 is the G46 equivalent of the RB500 bracket range, dimensioned for the wider and deeper G46 section.
Compatibility: G46 moulded cast iron gutter 125mm and 150mm only. For specification support, call 0333 987 4452.

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 classes. A linseed oil paint finish is also available, which is particularly appropriate for conservation projects.

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.
The Ornamental Airbrick is most appropriate on Victorian Gothic buildings — churches, chapels, vicarages, almshouses, collegiate buildings, and high-specification estate architecture — where decorative ironwork was part of the original design. It suits listed building replacements in kind and heritage new build where period accuracy in detailing is expected.
The physical properties of cast iron are sustained throughout its working life, so with proper maintenance we'd expect our gutters and pipes to last over 100 years under normal conditions.
A hit and miss vent has a sliding plate on the back of the grille that can be opened, partially restricted, or closed entirely without removing the vent from the wall. This allows airflow to be controlled from inside the building, making it suitable for underfloor void ventilation and through-wall ventilation where adjustable airflow is needed.
The Paxton H82 is a large-format hopper with decorative collar mouldings, making it particularly well suited to late Victorian and Edwardian buildings where the rainwater system forms part of the architectural composition. Typical applications include commercial heritage buildings, civic buildings, large detached houses, institutional premises, and warehouse conversions where a more substantial fitting is appropriate.
Cast iron hopper heads from Tuscan Foundry are available in Standard Black (a factory-applied primer and topcoat finish) and Heritage Colours. A linseed oil paint finish is also available, providing a vapour-permeable, historically authentic coating that is particularly appropriate for listed buildings and conservation projects. Full finish specifications are available from the team.
