Side rafter rise and fall bracket for common Og cast iron gutter.
Sizes available:

115mm (4.5″)
125mm (5″)
We also manufacture side rafter rise and fall brackets for common Og guttering made by: Osma, Marley, Hunter and Lindab
The RB501COG is a side rafter rise and fall bracket for the common ogee cast iron gutter. Where there is no fascia board — on open eaves, or where the rafter face is the only available fixing point — the RB501COG mounts directly to the side face of the rafter and provides adjustable support at the correct height for the common OG gutter run. The bracket cup is shaped for the ogee S-curve profile.
The threaded rise and fall cup allows precise fall setting at each bracket position independently of the rafter pitch, eliminating shimming and packing on long runs or where the roof line is uneven. 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, making it a practical bracket solution on mixed or partial replacement installations. Specified on listed buildings, heritage conservation projects, and period properties across England and Wales where the common ogee is the correct profile.
Compatibility: Common ogee gutter 100mm, 115mm, 125mm. Also suits Osma, Marley, Hunter, and Lindab common OG. For specification support, call 0333 987 4452.

Yes. The ornamental foliate pattern was widely used in Victorian construction and is appropriate for Grade II listed buildings and conservation area properties. Its decorative character is often preferable to a plain pattern on prominent or formal elevations. We recommend confirming the pattern with your conservation officer as part of any listed building consent application.
The H1A is available with round pipe connections in 65mm, 75mm, 100mm, and 150mm diameters. Please specify your required connection size when ordering, as this determines the SKU. If you are unsure of the correct pipe size for your project, our team can advise — call 0333 987 4452.
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.
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.

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.
Prices are shown on each product page. For project quantities, conservation specifications, or to discuss suitability for a listed building, call 0333 987 4452 or use the contact form.
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 Vent suits Victorian and Edwardian buildings where decorative cast iron or brass ventilation grilles were part of the original specification — including terrace houses, civic buildings, churches, entrance halls, and estate properties. It is appropriate on listed buildings and conservation area properties as a like-for-like decorative vent replacement, and on new heritage-quality construction where period detailing is required.
