Available in two sizes: 225mm x 82mm (single airbrick course height) and 225mm x 150mm (double course height). Both sizes fit standard brick coursing positions and install flush into the wall face.

Side rafter rise and fall bracket for G46 cast iron gutter.
Sizes available:
100mm x 75mm
125mm x 75mm
We also manufacture side rafter rise and fall brackets for moulded and Og guttering made by: Osma, Marley, Hunter and Lindab
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 drainage and guttering market has matured considerably over the past 20 years and there are now many more product choices for consumers to consider.
Despite the influx of new materials it appears that the benchmark for rainwater systems is still cast iron. Cast iron rainwater goods were introduced in the late 18th Century as an alternative to lead. As well as being easier to produce, the material enabled eaves gutters to be installed more simply, since lead could only be used in this location as a lining for timber gutters.
Many modern materials focus on replicating the appearance of cast iron but those materials can vary rarely offer any of the benefits. Cast iron gutters and pipes offer great strength and durability, a proven history of long life, low noise operation and fire resistance. Most old buildings have cast iron rainwater systems that should be maintained and preserved however; these inherent benefits make cast iron an ideal choice for both traditional and modern installations.
It is not uncommon to see modern alternative products marketed with terms like low maintenance or easy to install and cost effective. It has even been said that ‘plastic guttering systems provide a way of achieving a traditional look with modern convenience’. These terms tend to refer to possible cost savings rather than any real product benefits. It is also difficult to quantify the benefits of modern convenience over traditional build quality.
It is worth remembering that all rainwater goods will require some element of maintaining to ensure they are unblocked by debris and remain functional. No rainwater system cleans itself. Today most suppliers of cast iron rainwater systems offer products in both primer or pre-painted with a 10 year protective coating. When describing modern materials, the term ‘cost effective’ is used rather than simply saying cheap. There is no doubt that the initial cost of many modern materials is less than cast iron but you might be surprised to know that over its lifespan, cast iron will cost around a third of plastic.
It is easy to forget about your rainwater system but it does need to be maintained and inspected at least twice a year regardless of the product material. It does not matter whether the property is hundreds of years old or brand new, the message is the same; ‘maintaining your rainwater system contributes to the external appearance of the building as well as keeping it free from damp and structural damage.
A pole winder opener has a fixed-length arm, making it suited to standard rooflight positions with a consistent throw. A telescopic opener has an adjustable shaft, allowing it to accommodate varying rooflight positions and throw requirements. For guidance on which suits your project, call 0333 987 4452.
The Ornamental Airbrick (OAB) is available in three sizes: 225mm × 75mm (2.8kg), 225mm × 150mm (4.1kg), and 225mm × 225mm (5.8kg). All sizes have a uniform depth of 75mm, making them consistent to install across a subfloor ventilation course.
The Polished Brass finish suits buildings where brass metalwork was standard — formal Victorian terrace housing, civic and institutional buildings, and high-quality estate architecture. It is appropriate on listed buildings and conservation properties where the wider ironmongery specification is in brass and a matching material is required.
The right size depends on the width of your gutter run and the volume of water you need to collect. The Strayton H42A is available in four widths: 305mm (12"), 355mm (14"), 457mm (18"), and 610mm (24"). As a general guide, wider hoppers suit larger roof areas and heavier rainfall zones. If you are unsure, our team can advise based on your gutter profile and catchment area — call 0333 987 4452.
The H1A is available with round pipe connections in 65mm, 75mm, 100mm, and 150mm diameters. Please specify your required connection size when ordering, as this determines the SKU. If you are unsure of the correct pipe size for your project, our team can advise — call 0333 987 4452.
Casting of iron is an imperfect processs. It is possible with some cast iron radiators that you will get minor imperfections in the surface finish. When radiators are painted this will reduce and over the years every additional coat of paint applied will provide a smoother more equal finish.
Yes. A polished brass finish is historically appropriate for period buildings and is generally acceptable to conservation officers for listed building projects. If you are unsure about the specification requirements for your project, we are happy to advise — call 0333 987 4452.
Satin chrome has a brushed, low-sheen finish suited to contemporary interiors, while polished chrome has a bright mirror finish. Both are available in the telescopic hand winder range at Tuscan Foundry. The choice typically depends on the existing ironmongery specification.
