The ORL-TRRF is a bespoke top rafter-mounted rise and fall gutter bracket, manufactured to suit the Osma Roofline half-round PVC guttering system. The top rafter bracket is the appropriate fixing solution where the bracket needs to be secured to the top surface of a rafter rather than the fascia face or rafter side — typically where roof construction or access conditions make top-fixing the most practical or structurally sound option.
The bracket features a right-angled galvanised steel rafter plate for top-surface fixing, combined with a threaded steel riser column and bow-and-pin gutter cup in black or grey. The adjustable riser provides full fall control along the gutter run. Compatible with the Osma Roofline 6T694 system, and designed as a functional equivalent to the Osma OT147G side rafter arm.
Used on open eaves and cut roof constructions where top rafter access is available and preferred, and on refurbishment projects where the existing roof structure dictates the fixing method. Suits both residential and light commercial applications with Osma Roofline guttering.
Manufactured to order in black or grey riser cup options. Lead time 10–14 working days from order confirmation.
System compatibility: Osma Roofline half-round guttering system. Replaces Osma OT147G side rafter arm. For specification queries, call 0333 987 4452.

The drainage and guttering market has matured considerably over the past 20 years and there are now many more product choices for consumers to consider.
Despite the influx of new materials it appears that the benchmark for rainwater systems is still cast iron. Cast iron rainwater goods were introduced in the late 18th Century as an alternative to lead. 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.
It is easy to forget about your rainwater system but it does need to be maintained and inspected at least twice a year regardless of the product material. It does not matter whether the property is hundreds of years old or brand new, the message is the same; ‘maintaining your rainwater system contributes to the external appearance of the building as well as keeping it free from damp and structural damage.
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.
Hopper heads are supplied in red oxide primer ready for on-site painting, or pre-finished in black. A full range of Heritage Colours in traditional linseed oil paint is also available on request — please contact us for the swatch chart.
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.
Our cast iron airbricks are available in three standard sizes: 225mm × 75mm (single course), 225mm × 150mm (double course), and 225mm × 225mm (square format). These correspond to the standard airbrick positions used in Victorian and Edwardian brickwork. Each size is available across the School Board, Louvre, and Ornamental pattern ranges.
The Iron Works Patterned Hit & Miss Vents are available in two sizes: 225mm × 82mm (single-course, suitable for standard airbrick positions) and 225mm × 150mm (double-course format). Both sizes are available in all three finishes: Antique Black, Polished Lacquered, and Polished Brass.
Our bespoke rise and fall gutter brackets — including fascia, side rafter, and top rafter variants for Osma Roofline and Osma SuperLine systems — are manufactured to order. The standard lead time is 10–14 working days from receipt of a confirmed order. If you have a programme deadline, please call us on 0333 987 4452 and we will advise on current availability.
