The OSRL-TRRF is a bespoke top rafter-mounted rise and fall gutter bracket, manufactured to suit the Wavin Osma Roundline half-round PVC guttering system. The top rafter variant is required where the fixing is to be made to the top surface of a rafter — on open eaves, cut roof constructions, or where the roof structure makes top-fixing the most practical option.
The bracket features a right-angled galvanised steel rafter plate for top-surface fixing, combined with a threaded steel riser column and a half-round bow-and-pin gutter cup compatible with the Roundline system. The adjustable riser allows fall to be set at the correct gradient along the run independently of roof pitch. Available in black or grey riser cup options.
Used on open eaves and cut roof constructions with Wavin Osma Roundline guttering, and on refurbishment projects where the existing roof structure dictates the fixing approach. Suitable for residential and light commercial applications.
Manufactured to order in black or grey. Lead time 10–14 working days from order confirmation.
System compatibility: Wavin Osma Roundline half-round PVC guttering system. For specification queries, call 0333 987 4452.

Our cast iron hopper heads are available in a standard primed and black-painted finish, ready for on-site topcoats. Heritage colour finishes and factory-applied linseed oil paint are available on request. Linseed oil paint is a vapour-permeable, period-appropriate finish particularly well suited to listed buildings and conservation area properties.
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.
Satin chrome has a brushed, low-sheen finish suited to contemporary interiors, while polished chrome has a bright mirror finish. Both are available in the telescopic hand winder range at Tuscan Foundry. The choice typically depends on the existing ironmongery specification.

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.
Our cast iron hopper heads are available in a standard primed and black-painted finish, ready for on-site topcoats. Heritage colour finishes and factory-applied linseed oil paint are available on request. Linseed oil paint is a vapour-permeable, period-appropriate finish particularly well suited to listed buildings and conservation area properties.
Linseed oil paint is the most appropriate finish for cast iron guttering on listed and historic buildings. It is breathable, flexible, and penetrating — qualities that suit the movement characteristics of cast iron through seasonal temperature changes. Tuscan Foundry Products offers a curated range of heritage linseed oil colours. For modern applications, a high-quality exterior oil-based paint system over a metal primer is also acceptable.
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.
