The plain rain diverter kit fits into a cast iron round downpipe run to collect roof water into a water butt, while keeping a traditional cast iron appearance.
The diverter replaces a short section of pipe and takes water off to the butt, returning the flow to the downpipe once the butt is full. As a plain fitting it suits non-eared pipe runs fixed with holdfasts, screw-to-wall brackets or ornamental earbands. An eared version is also available.
It suits garden elevations, outbuildings, stable yards, walled gardens and kitchen garden buildings on heritage properties, where water harvesting is wanted without introducing plastic fittings into a cast iron system.
Sizes: 65mm (2½″), 75mm (3″) and 100mm (4″) diameter.
Cast in solid grey iron in the UK to BS 460, and supplied primed for site painting or factory black painted. Linseed oil paint finishes can be quoted on request.

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.
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 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.
The Strayton H42A accepts round, square, and rectangular pipe connections. Round: 65mm, 75mm, and 100mm. Square: 75×75mm, 100×100mm, and 125×125mm. Rectangular: 100×75mm, 125×100mm, and 150×100mm. Please specify your required connection size when ordering.
The Antique Black finish suits Victorian, Edwardian, and inter-war buildings where ventilation ironwork was painted rather than polished — estate houses, terrace housing, civic buildings, and rural properties. It is also correct for listed buildings and conservation area properties requiring like-for-like replacement of original ornamental cast iron vents.
Yes. A polished brass finish is historically appropriate for period buildings and is generally acceptable to conservation officers for listed building projects. If you are unsure about the specification requirements for your project, we are happy to advise — call 0333 987 4452.

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.
