Top rafter rise and fall bracket for G46 cast iron gutter.

We also manufacture top rafter rise and fall brackets for Og and moulded gutters made by: Osma, Marley, Hunter and Lindab
The RB500G46 is a top rafter rise and fall bracket for the G46 moulded cast iron gutter. Where open eaves construction or the absence of a fascia board requires fixing to the top surface of a rafter, the RB500G46 provides a secure, adjustable support that allows precise fall setting across the gutter run. The bracket cup is dimensioned specifically for the G46 moulded section — the larger Victorian and Edwardian ogee profile — ensuring a correctly seated fit.
Available in both G46 profile sizes: 125mm (5″) and 150mm (6″). Zinc-plated steel finish for outdoor corrosion resistance. The threaded rise and fall cup eliminates shimming and allows accurate gradient control on long runs or complex roof lines, which is particularly important on the large Victorian and Edwardian buildings where the G46 profile is commonly found.
Specified on listed buildings and heritage restoration projects where the G46 moulded pattern is the historically correct profile. The RB500G46 is the G46 equivalent of the RB500 bracket range, dimensioned for the wider and deeper G46 section.
Compatibility: G46 moulded cast iron gutter 125mm and 150mm only. For specification support, call 0333 987 4452.

The satin chrome telescopic rooflight hand winder is well suited to contemporary and transitional interiors where a brushed chrome finish complements modern or minimal ironmongery. It is compatible with Lumen Rooflights and timber-framed skylights.

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.
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.
A hit and miss vent has a sliding plate on the back of the grille that can be opened, partially restricted, or closed entirely without removing the vent from the wall. This allows airflow to be controlled from inside the building, making it suitable for underfloor void ventilation and through-wall ventilation where adjustable airflow is needed.
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.
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.
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.
The in-house Premier Extra coating is formulated for a life expectancy of around 10 years under normal weather conditions, provided any impact damage or surface scuffing is made good promptly. Coastal locations or higher pollution levels can shorten this, so it's worth asking your local stockist or paint manufacturer for site-specific advice.
