The RB500COG is a top rafter rise and fall bracket for the common ogee cast iron gutter. Where open eaves construction or the absence of a fascia board requires fixing to the top surface of the rafter, the RB500COG provides a secure, adjustable support that allows precise fall setting across the gutter run. The bracket cup is shaped for the ogee S-curve profile of the common OG gutter.
The threaded rise and fall cup allows the gutter height to be set accurately at each bracket position regardless of rafter pitch, eliminating the need for shimming or packing. Available in three sizes to suit the standard common ogee range: 100mm (4″), 115mm (4.5″), and 125mm (5″).
Also compatible with common ogee guttering manufactured by Osma, Marley, Hunter, and Lindab. Specified on listed buildings, heritage conservation projects, and period properties across England and Wales where the common ogee is the correct profile and open eaves construction requires top-rafter fixing.
Compatibility: Common ogee gutter 100mm, 115mm, 125mm. Also suits Osma, Marley, Hunter, and Lindab common OG. For specification support, call 0333 987 4452.

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 H543 measures 504mm wide x 185mm deep x 200mm high, making it well suited to wide, shallow proportions that suit box-gutter outlets on period roofs, terraces and commercial premises.
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 H460 is well suited to Georgian, Regency, and Victorian buildings where a plain, undecorated rectangular hopper is the appropriate choice — particularly listed properties, conservation area buildings, and institutional or commercial buildings in historic town centres. Its clean, restrained form makes it equally appropriate on modern heritage-style construction where period accuracy is required without ornamental detail.
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.
Yes. Polished brass ironmongery is historically appropriate for period buildings and is generally acceptable to conservation officers for listed building projects. If you require confirmation for your specific scheme, we are happy to advise — call 0333 987 4452.
The H540 measures 600mm wide x 340mm deep x 475mm high, making it well suited to substantial country houses, civic and ecclesiastical buildings.
