Fascia rise and fall bracket for common Og cast iron gutter.
Sizes available:
100mm (4″)
115mm (4.5″)
125mm (5″)
We also manufacture fascia rise and fall brackets for common Og guttering made by: Osma, Marley, Hunter and Lindab
The RB502COG is a fascia-mounted rise and fall bracket for the common ogee cast iron gutter. Where a standard fixed fascia bracket cannot achieve precise fall control — on older properties with settled fascia boards, long gutter runs, or where the gradient must be set independently of the fascia angle — the RB502COG’s adjustable mechanism provides the correct solution. The bracket cup is shaped for the ogee S-curve profile of the common OG gutter.
The threaded rise and fall cup eliminates shimming and packing and allows accurate gradient setting across the full run. 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. Widely specified on listed buildings and heritage conservation projects across England and Wales where the common ogee is the historically correct profile and precise fall control on long or complex runs is required.
Compatibility: Common ogee gutter 100mm, 115mm, 125mm. Also suits Osma, Marley, Hunter, and Lindab common OG. For specification support, call 0333 987 4452.

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. 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.
The right size depends on the width of your gutter run and the volume of water you need to collect. The Strayton H42A is available in four widths: 305mm (12"), 355mm (14"), 457mm (18"), and 610mm (24"). As a general guide, wider hoppers suit larger roof areas and heavier rainfall zones. If you are unsure, our team can advise based on your gutter profile and catchment area — call 0333 987 4452.
Yes. Our telescopic screw-jack openers and pole-operated handles are compatible with Lumen Rooflight systems. They are also suitable for use with other timber-framed rooflights and skylights fitted with appropriate catches or stays. If you are unsure of compatibility, call us on 0333 987 4452 and we can advise.
Premier Extra is our ready-to-fix factory finish — an attractive black semi-gloss coating that needs no painting on site, available across all seven standard gutter profiles and round rainwater pipes. It's also available to special order in a wider range of RAL and BS colours.
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.
For rooflights directly above a worktop or sink, a telescopic screw-jack hand winder is the most practical choice. Available in polished brass, satin chrome, and polished chrome, these openers allow controlled ventilation from a fixed handle position without requiring a pole. The 150mm or 250mm size is typically appropriate for standard-height kitchen rooflights.
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 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.
Yes. Cast iron airbricks are frequently specified for listed buildings and conservation area properties precisely because they replicate the material and pattern of the original Victorian and Edwardian ventilation grilles. Local conservation officers and building control typically accept like-for-like cast iron replacements without objection. We can provide product specifications and material datasheets to support applications.
