The RB501G46 is a side rafter rise and fall bracket for the G46 moulded cast iron gutter. Where there is no fascia board — on open eaves, or where the rafter face is the only available fixing point — the RB501G46 mounts directly to the side face of the rafter and provides adjustable support at the correct height for the gutter run. The bracket cup is shaped specifically for the G46 moulded section.
Available in both G46 profile sizes: 125mm (5″) and 150mm (6″). Zinc-plated steel finish. The threaded rise and fall cup allows precise fall setting at each bracket position independently of the rafter pitch — important on the large Victorian and Edwardian buildings where the G46 is the standard profile and long gutter runs require accurate gradient management.
Specified on listed buildings and heritage restoration projects where the G46 moulded pattern is the historically correct profile. The RB501G46 is the G46 equivalent of the RB501 bracket range.
Compatibility: G46 moulded cast iron gutter 125mm and 150mm only. For specification support, call 0333 987 4452.

The Ornamental Airbrick (OAB) is available in three sizes: 225mm × 75mm (2.8kg), 225mm × 150mm (4.1kg), and 225mm × 225mm (5.8kg). All sizes have a uniform depth of 75mm, making them consistent to install across a subfloor ventilation course.
The Antique Black finish suits Victorian, Edwardian, and inter-war buildings where ventilation ironwork was painted rather than polished — estate houses, terrace housing, civic buildings, and rural properties. It is also correct for listed buildings and conservation area properties requiring like-for-like replacement of original ornamental cast iron vents.
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.

Yes. Cast iron airbricks are the appropriate material for listed buildings and conservation area properties where the original ventilation grilles were cast iron. They maintain the character and material authenticity required by most conservation officers and listed building consent conditions. We recommend confirming the specific pattern with your conservation officer before ordering.
The H534 measures 430mm wide x 240mm deep x 366mm high, making it well suited to Victorian villas and townhouses.
The H527 measures 430mm wide x 195mm deep x 540mm high, making it well suited to Victorian villas and townhouses where a decorative leader head is wanted.
