Top rafter rise and fall bracket for deep half round cast iron gutter.
Sizes available:
100mm x 75mm
125mm x 75mm
We also manufacture top rafter rise and fall brackets for deep half round guttering made by: Osma, Marley, Hunter and Lindab
The RB500DH is a zinc-plated top rafter rise and fall bracket for plain deep half round cast iron guttering. Where open eaves construction or the absence of a fascia board requires fixing directly to the top surface of a rafter, the RB500DH provides a secure and adjustable support that allows precise fall setting along the gutter run.
The bracket features a zinc-plated steel rafter arm designed for top-surface rafter fixing, combined with a threaded rise and fall cup that adjusts the gutter height at each bracket position independently of the rafter pitch. Available in four sizes to suit all standard deep half round gutter profiles: 100mm (4″), 115mm (4.5″), 125mm (5″), and 150mm (6″).
Commonly specified on listed building and heritage restoration projects involving deep half round cast iron guttering, and on new construction where exposed rafters and open eaves are a feature of the design. The rise and fall mechanism eliminates the need to pack or shim the bracket, allowing accurate gradient setting across long gutter runs or on complex roof lines.
Zinc-plated finish provides corrosion resistance for outdoor use. The RB500DH is the deep half round equivalent of the RB500 bracket, dimensioned specifically for the wider and deeper profile of the deep half round section.
Compatibility: Plain deep half round cast iron gutter profiles 100mm, 115mm, 125mm, and 150mm. For project specification, call 0333 987 4452.

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 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.
Our cast iron airbricks are available in three standard sizes: 225mm × 75mm (single course), 225mm × 150mm (double course), and 225mm × 225mm (square format). These correspond to the standard airbrick positions used in Victorian and Edwardian brickwork. Each size is available across the School Board, Louvre, and Ornamental pattern ranges.
The Brass Rooflight Pole Winder Opener 300mm is a screw-jack operated rooflight opener designed for manual control of timber-framed skylights and Lumen Rooflights. The 300mm fixed arm is suited to standard rooflight positions and is finished in polished brass.
The Pultney Tapered Hopper Head is well suited to Georgian and Regency townhouses, Victorian terraces, rural farmhouses, barns, and functional estate buildings where a plain, period-correct hopper is the appropriate specification. It also works well on new heritage-style construction. Its unfussy, chamfered form makes it a versatile choice across a wide range of traditional building types.
The Gothic foliate tracery design of the Ornamental Airbrick provides a good free-flow ventilation area relative to its face size. The open area is comparable to other standard cast iron airbrick patterns. The visual density of the pattern at a distance reads as solid ironwork, which suits formal and decorative elevations without compromising subfloor ventilation effectiveness.
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 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.
We are able to place dates and initials and insignia onto most of our flat faced rainwater hopper heads.
