Marksham Cast Iron Hopper Head No.108

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.

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.

Our cast iron hopper heads are available in a choice of finishes including primer, painted, and specialist heritage finishes. Please call us on 0333 987 4452 or submit an enquiry to discuss the right finish for your project.

Our standard spike or sturt length is 300mm (12″). Other sizes are available upon request.

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.

Yes. All our mild steel brackets are supplied in either silver or black zinc plate. This coating protects the metal however, both will need painting prior to installation.

We have chosen to use zinc plating for two reasons; firstly that it is a more environmentally friendly than galvanising and secondly that it does not block up the threaded part of the rise and fall cups in the way that galvanising does.

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.

Our hopper heads are available with a wide range of pipe connections to suit round, square, and rectangular downpipes. The Calnethorpe No.11 accepts round 65mm, 75mm, and 100mm; square 75×75mm, 100×100mm, and 125×125mm; and rectangular 100×75mm, 125×100mm, and 150×100mm. Connection options vary by model — please contact us to confirm availability for your chosen hopper.

It is possible for us to supply towel warmers with an electric heating element in them. The Electrad system is a unique system available to us, that enables independent heating of towel rails and radiators via the properties electrical system.

Casting of iron is an imperfect processs. It is possible with some cast iron radiators that you will get minor imperfections in the surface finish. When radiators are painted this will reduce and over the years every additional coat of paint applied will provide a smoother more equal finish.
