The RB500 is a zinc-plated top rafter rise and fall bracket for plain half round cast iron guttering. Where a fixed bracket is not appropriate — on open eaves, cut roof constructions, or where the rafter provides the only available fixing point — the top rafter bracket provides a secure, adjustable support mounted directly to the top surface of the rafter.
The bracket features a zinc-plated steel rafter arm for top-surface 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 all standard cast iron half round gutter profiles: 100mm (4″), 115mm (4.5″), 125mm (5″), and 150mm (6″).
Suited to new construction with exposed rafters, heritage restoration projects where a continuous fascia board is absent, and any situation where top rafter fixing is structurally preferred. Commonly specified alongside cast iron half round gutter sections and angle fittings on period and listed building projects where precise fall control is critical to long-term performance.
The rise and fall mechanism eliminates the need to pack or shim the bracket, allowing accurate gradient setting across long gutter runs on uneven or complex roof lines. Zinc-plated finish provides corrosion resistance for outdoor use.
Compatibility: Cast iron half round gutter profiles 100mm, 115mm, 125mm, and 150mm. For technical queries or project specification support, call 0333 987 4452.

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.
We do offer a range of Ogee patterned gutters in both straight and radius profiles. The straight profiles are much more common and as such cost less.
The H543 measures 504mm wide x 185mm deep x 200mm high, making it well suited to wide, shallow proportions that suit box-gutter outlets on period roofs, terraces and commercial premises.
Our cast iron hopper heads are available with 65mm, 75mm and 100mm round outlets, 75mm, 100mm and 125mm square outlets, and 100x75mm, 125x100mm and 150x125mm rectangular outlets, to match the downpipe already on site or specified for the project.
Our cast iron airbricks are available in a choice of finishes including primer and painted options. If you require a specific finish for a conservation project or to match existing ironwork, please call us on 0333 987 4452 to discuss.
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.
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.
The H541 measures 274mm wide x 130mm deep x 330mm high, making it well suited to a slender profile suited to narrow Georgian townhouses and terraces where space is limited.
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.
