Clear

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.

What finishes are available on your cast iron hopper heads?

What finishes are available on your cast iron hopper heads?

Cast iron hopper heads from Tuscan Foundry are available in Standard Black (a factory-applied primer and topcoat finish) and Heritage Colours. A linseed oil paint finish is also available, providing a vapour-permeable, historically authentic coating that is particularly appropriate for listed buildings and conservation projects. Full finish specifications are available from the team.

What is the advantage of a louvre-face airbrick over a square-grid pattern?

What is the advantage of a louvre-face airbrick over a square-grid pattern?

The louvre face provides directional airflow and offers some resistance to driven rain entering the subfloor void, making it a practical choice for exposed elevations or properties in areas with significant prevailing wind and rainfall. The square-grid (school board) pattern offers a larger open ventilation area but less weather protection.

Is a cast iron airbrick suitable for use on a listed building?

Is a cast iron airbrick suitable for use on a listed building?

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.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

BTU stand’s for British Thermal Units. This was the old (Imperial) measurement for heat in connection with plumbing. Although BTU’s is a term still commonly used within the heating and plumbing, the industry is now going over to KW’s Kilowatts.

What building types is the Rectangular Box Cast Iron Hopper Head Plain No.46 (H460) suited to?

What building types is the Rectangular Box Cast Iron Hopper Head Plain No.46 (H460) suited to?

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.

What size cast iron hopper head do I need for my project?

What size cast iron hopper head do I need for my project?

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.
