The Rectangular Pipe to Round Connector provides a transition fitting between a cast iron rectangular downpipe and a cast iron round downpipe, allowing the two pipe systems to be joined cleanly in a single run. Used where a rectangular pipe at the upper part of the elevation transitions to a round pipe — for example where the rectangular section connects to a round underground drainage system, or where an existing round pipe is being connected to a new rectangular installation above.
An important practical fitting on heritage restoration projects where the existing above-ground pipe is rectangular and the below-ground or transition pipework is round. Manufactured in cast iron to BS 460:2002. Available in sizes to suit the standard rectangular pipe range. For specification support, call 0333 987 4452.

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.
Victorian properties most commonly used Ogee (OG) gutter profiles, including the standard Cast Iron Ogee and the G46 Moulded Ogee. Half Round guttering was also widely used, particularly in the later Victorian period. The correct profile depends on what is already present on the building — we recommend inspecting any surviving sections and matching the profile, size, and socket direction exactly. We supply 19 standard gutter profiles and can copy-cast any non-standard profile from a drawing, photograph, or physical sample.
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.
We do offer a range of Ogee patterned gutters in both straight and radius profiles. The straight profiles are much more common and as such cost less.

The satin chrome telescopic rooflight hand winder opener is available in multiple sizes. The telescopic mechanism adjusts to accommodate varying rooflight positions and throw requirements. For a full list of available sizes, visit tuscanfoundry.com or call 0333 987 4452.
Yes — we strongly recommend painting all products before installation to ensure full coverage on every surface, which reduces long-term maintenance. Standard Premier Rainwater products are supplied in a grey metal primer with rust inhibitors and need two undercoats and one top coat (or one undercoat and two top coats) of a good quality exterior paint.
Yes. Polished brass is a historically appropriate finish for period and listed buildings and is generally acceptable to conservation officers. If your project requires specific confirmation, we are happy to advise — call 0333 987 4452.
