Top rafter rise and fall bracket for half round cast iron guttering. Our zinc plated
top rafter rise and fall gutter bracket is available in the following sizes:
100mm (4″)
115mm (4.5″)
125mm (5″)
150mm (6″)
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.

The Cast Iron Louvre Airbrick suits Victorian and Edwardian terraced housing, semi-detached properties, public houses, agricultural buildings, and workshop structures where the original airbrick was a louvre-face grille. The horizontal fin profile is widely found in British domestic and light industrial construction from the 1870s through to the 1950s.
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.

Yes. Bespoke copy casting is a core service at Tuscan Foundry Products. We can replicate any cast iron gutter, downpipe, hopper head, or fitting from drawings, detailed photographs, or a physical sample or surviving section. Each commission is assessed individually. Lead time is typically 8 to 10 weeks, and quantities as low as a single piece can be considered depending on pattern-making costs.

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 Calnethorpe is designed for formal classical and Georgian elevations where scale and material authenticity matter — large townhouses, country houses, manor houses, and institutional buildings. It is also widely specified for new-build heritage projects where cast iron rainwater goods are required to conservation standard.
Cast iron hopper heads are priced on enquiry due to the range of connection and finish options available. Please call us on 0333 987 4452 or use the contact form and we will respond promptly with a quotation tailored to your project requirements.
BTU stand’s for British Thermal Units. This was the old (Imperial) measurement for heat in connection with plumbing. Although BTU’s is a term still commonly used within the heating and plumbing, the industry is now going over to KW’s Kilowatts.
Our standard spike or sturt length is 300mm (12″). Other sizes are available upon request.
