RB500 – Top Rafter Rise and Fall Bracket for Plain Half Round Gutter

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.

Georgian properties typically used Half Round or ogee-style guttering, often in larger sizes to handle the roof areas of substantial period buildings. Large sand cast gutter profiles are appropriate for grander Georgian architecture, particularly country houses, institutions, and formal terraces. If the original guttering has been lost or damaged, a site survey can establish the most appropriate profile from the building

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 Cast Iron Louvre Airbrick suits Victorian, Edwardian, and inter-war residential and commercial properties where the louvre-pattern vent was the standard specification. It is the correct like-for-like replacement on listed buildings and conservation area properties, and suits new heritage-style construction requiring an authentic period ventilation grille.

A corner hopper head collects rainwater from two gutters running at right angles and channels it into a single downpipe. They are typically required at internal roof valleys, on hipped roofs, and wherever two runs of gutter converge at a corner. The Regent H1A is designed specifically for this application and is sized to suit the most common gutter profiles.

Yes. Cast iron airbricks are frequently specified for listed buildings and conservation area properties precisely because they replicate the material and pattern of the original Victorian and Edwardian ventilation grilles. Local conservation officers and building control typically accept like-for-like cast iron replacements without objection. We can provide product specifications and material datasheets to support applications.

Victorian properties most commonly used Ogee (OG) gutter profiles, including the standard Cast Iron Ogee and the G46 Moulded Ogee. Half Round guttering was also widely used, particularly in the later Victorian period. The correct profile depends on what is already present on the building — we recommend inspecting any surviving sections and matching the profile, size, and socket direction exactly. We supply 19 standard gutter profiles and can copy-cast any non-standard profile from a drawing, photograph, or physical sample.

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.
