Cast iron plain loose socket for rectangular downpipes, 100x75mm to 150x100mm, in primer or black painted finish.
UK delivery from £30. Fittings are despatched boxed. See delivery rates.
The Rectangular Pipe Socket Plain is a separate cast iron socket without ears. It slips over a spigot to make a joint at any point in a rectangular downpipe run fixed with holderbats or earbands.
It is used where a plain pipe has been cut and the socket end lost, or where two spigot ends must be joined. The moulded band matches the socket on plain pipe so the joint reads correctly on the elevation.
Where a fixing is needed at the joint, use the Rectangular Pipe Loose Eared Socket.
All fittings in our rectangular range are cast iron to BS 460:2002, made to the same moulded profile so pipes and fittings line up neatly on the elevation. Every fitting is supplied either in primer, ready for painting on site, or in factory black. For listed buildings and conservation areas we also offer hand-applied linseed oil paint in heritage colours, which stays breathable and flexible and is straightforward to maintain. Stocked items are usually dispatched within 5 to 7 working days; allow around 6 to 7 weeks where a linseed oil finish is specified.
Rectangular pipe sizes: 100mm x 75mm (4″ x 3″), 125mm x 70mm, 125mm x 100mm (5″ x 4″) and 150mm x 100mm (6″ x 4″).
Suitable for listed buildings, conservation areas and heritage restoration. For specification support or a project quotation, call 0333 987 4452.

The Cast Iron Louvre Airbrick suits Victorian, Edwardian, and inter-war residential and commercial properties where the louvre-pattern vent was the standard specification. It is the correct like-for-like replacement on listed buildings and conservation area properties, and suits new heritage-style construction requiring an authentic period ventilation grille.
The Regent H1 is well suited to Victorian and Edwardian terraces, listed commercial buildings, civic and institutional properties, and ecclesiastical buildings where a traditional funnel-form hopper is architecturally appropriate. Its multi-faceted tapering body reads as period-accurate on Gothic and classical building types alike, and it is a commonly specified choice for conservation and listed building projects across the UK.
Linseed oil paint is the most appropriate finish for cast iron guttering on listed and historic buildings. It is breathable, flexible, and penetrating — qualities that suit the movement characteristics of cast iron through seasonal temperature changes. Tuscan Foundry Products offers a curated range of heritage linseed oil colours. For modern applications, a high-quality exterior oil-based paint system over a metal primer is also acceptable.
The Iron Works Patterned Hit & Miss Vents are available in two sizes: 225mm × 82mm (single-course, suitable for standard airbrick positions) and 225mm × 150mm (double-course format). Both sizes are available in all three finishes: Antique Black, Polished Lacquered, and Polished Brass.
Yes. Cast iron ornamental vents in period patterns are frequently specified on listed buildings and conservation area properties as like-for-like replacements for original Victorian ironwork. Conservation officers generally accept cast iron in period patterns without objection. We can supply specifications to support planning and listed building consent applications.
The H541 measures 274mm wide x 130mm deep x 330mm high, making it well suited to a slender profile suited to narrow Georgian townhouses and terraces where space is limited.

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.
It is possible for us to supply towel warmers with an electric heating element in them. The Electrad system is a unique system available to us, that enables independent heating of towel rails and radiators via the properties electrical system.
