The RB501DH is a zinc-plated side rafter rise and fall bracket for plain deep half round cast iron guttering. Where there is no fascia board — on open eaves, timber-framed buildings, or structures where rafter-face fixing is preferred — the RB501DH provides a secure, adjustable support mounted directly to the side face of the rafter.
The bracket features a zinc-plated steel rafter arm for side-face fixing, combined with a threaded rise and fall cup that allows gutter fall to be set precisely at each bracket position. Available in four sizes to suit the standard range of deep half round gutter profiles: 100mm (4″), 115mm (4.5″), 125mm (5″), and 150mm (6″).
Typically specified on heritage and conservation projects involving deep half round cast iron guttering where the roof construction dictates rafter-face rather than fascia fixing. Also used on refurbishment projects where the original fascia board is absent, damaged, or structurally unsuitable as a fixing surface.
The rise and fall cup allows precise gradient control along the gutter run regardless of rafter angle, eliminating the need for shimming or packing. Zinc-plated finish for outdoor corrosion resistance.
Compatibility: Plain deep half round cast iron gutter profiles 100mm, 115mm, 125mm, and 150mm. For project specification, call 0333 987 4452.

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.
Size selection depends on the distance between the mounting point and the rooflight frame, and the desired throw (opening distance). Our telescopic openers are available in 150mm, 250mm, and 300mm; the screw-jack stay is available in 300mm with a 250mm throw. For guidance on sizing for your specific rooflight, please call 0333 987 4452 or use the contact form.
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 Cast Iron Louvre Airbrick (F020802AFC) is available in 225mm × 75mm, 225mm × 150mm, and 225mm × 225mm — standard brick course heights. All sizes share a consistent depth for straightforward like-for-like replacement of original cast iron louvre airbricks.
The Antique Black cast iron version is suitable for external use. The Polished Lacquered version is best suited to interiors or sheltered external locations where the polished finish will be protected from weathering. The Polished Brass version is suited to interior and semi-exposed locations. For external applications on exposed elevations, the Antique Black finish is the recommended specification.
Yes, provided they are sized for the lower water temperature. Outputs are published at ΔT50; at ΔT30 a section gives about half that, so heat pump systems usually need more sections or a deeper pattern. We can prepare a radiator schedule at your heat pump design temperature.
Polished chrome has a bright mirror finish, while satin chrome has a brushed, low-sheen appearance. Both are available in the telescopic hand winder range. The finish choice typically depends on the ironmongery specification for the project.
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
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.
The H544 measures 380mm wide x 220mm deep x 418mm high, making it well suited to Georgian and Victorian townhouses and period commercial buildings.
