The RB501G46 is a side rafter rise and fall bracket for the G46 moulded cast iron gutter. Where there is no fascia board — on open eaves, or where the rafter face is the only available fixing point — the RB501G46 mounts directly to the side face of the rafter and provides adjustable support at the correct height for the gutter run. The bracket cup is shaped specifically for the G46 moulded section.
Available in both G46 profile sizes: 125mm (5″) and 150mm (6″). Zinc-plated steel finish. The threaded rise and fall cup allows precise fall setting at each bracket position independently of the rafter pitch — important on the large Victorian and Edwardian buildings where the G46 is the standard profile and long gutter runs require accurate gradient management.
Specified on listed buildings and heritage restoration projects where the G46 moulded pattern is the historically correct profile. The RB501G46 is the G46 equivalent of the RB501 bracket range.
Compatibility: G46 moulded cast iron gutter 125mm and 150mm only. For specification support, call 0333 987 4452.

The standards for our cast iron gutters and pipes have remained remarkably constant for many years. The physical properties of cast iron are sustained throughout its lifetime thus maintaining its effectiveness. Coupled with is durability and proper maintenance, we would expect our traditional cast iron rainwater products to last for over 50 years under normal conditions.

Yes. Polished brass ironmongery is historically appropriate for period buildings and is generally acceptable to conservation officers for listed building projects. If you require confirmation for your specific scheme, we are happy to advise — call 0333 987 4452.
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.
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.
For rooflights directly above a worktop or sink, a telescopic screw-jack hand winder is the most practical choice. Available in polished brass, satin chrome, and polished chrome, these openers allow controlled ventilation from a fixed handle position without requiring a pole. The 150mm or 250mm size is typically appropriate for standard-height kitchen rooflights.
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.
