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 School Board Airbrick suits Victorian and Edwardian institutional, civic, and residential buildings where the square-grid airbrick pattern was standard — including school buildings, civic halls, estate housing, terrace houses, and warehouses. It is also appropriate on listed buildings and conservation area properties as a like-for-like replacement for worn square-grid cast iron vents.
The physical properties of cast iron are sustained throughout its working life, so with proper maintenance we'd expect our gutters and pipes to last over 100 years under normal conditions.
The Antique Black finish is cast iron with a blackened surface — the most historically accurate finish for cast iron ironwork and the most appropriate for the majority of heritage applications. Polished Lacquered is cast iron with a bright polished surface sealed with clear lacquer, suited to interiors and sheltered locations where polished ironwork is the specification. Polished Brass is solid polished brass throughout — the correct choice where existing building fittings are in brass or where a warm metal tone is required.
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 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.
Our brackets are more commonly used on cast iron rainwater systems. Unlike plastic, cast iron is heavy and the weight keeps the gutter in position. As such our brackets do not normally have retaining clips which could lead to plastic or lightweight gutters blowing out of the bracket. The profile of your gutter should match that of our bracket but without the weight to keep it in place you may well encounter problems in bad weather.

The Ornamental Airbrick is most appropriate on Victorian Gothic buildings — churches, chapels, vicarages, almshouses, collegiate buildings, and high-specification estate architecture — where decorative ironwork was part of the original design. It suits listed building replacements in kind and heritage new build where period accuracy in detailing is expected.
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.
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.
