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.

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.
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.
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.
Hopper heads are supplied in red oxide primer ready for on-site painting, or pre-finished in black. A full range of Heritage Colours in traditional linseed oil paint is also available on request — please contact us for the swatch chart.
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 drainage and guttering market has matured considerably over the past 20 years and there are now many more product choices for consumers to consider.
Despite the influx of new materials it appears that the benchmark for rainwater systems is still cast iron. Cast iron rainwater goods were introduced in the late 18th Century as an alternative to lead. As well as being easier to produce, the material enabled eaves gutters to be installed more simply, since lead could only be used in this location as a lining for timber gutters.
Many modern materials focus on replicating the appearance of cast iron but those materials can vary rarely offer any of the benefits. Cast iron gutters and pipes offer great strength and durability, a proven history of long life, low noise operation and fire resistance. Most old buildings have cast iron rainwater systems that should be maintained and preserved however; these inherent benefits make cast iron an ideal choice for both traditional and modern installations.
It is not uncommon to see modern alternative products marketed with terms like low maintenance or easy to install and cost effective. It has even been said that ‘plastic guttering systems provide a way of achieving a traditional look with modern convenience’. These terms tend to refer to possible cost savings rather than any real product benefits. It is also difficult to quantify the benefits of modern convenience over traditional build quality.
It is worth remembering that all rainwater goods will require some element of maintaining to ensure they are unblocked by debris and remain functional. No rainwater system cleans itself. Today most suppliers of cast iron rainwater systems offer products in both primer or pre-painted with a 10 year protective coating. When describing modern materials, the term ‘cost effective’ is used rather than simply saying cheap. There is no doubt that the initial cost of many modern materials is less than cast iron but you might be surprised to know that over its lifespan, cast iron will cost around a third of plastic.
It is easy to forget about your rainwater system but it does need to be maintained and inspected at least twice a year regardless of the product material. It does not matter whether the property is hundreds of years old or brand new, the message is the same; ‘maintaining your rainwater system contributes to the external appearance of the building as well as keeping it free from damp and structural damage.
Traditional Express (TX) is a cast iron push-fit soil system. Socketless pipes are joined with push-fit sockets and couplings using rubber seals, so there is no caulking on site. LCC uses caulked socket-and-spigot joints and a bitumen coating. TX is quicker to install and can be painted; LCC is the closer match to an original Victorian stack. Our Traditional Express vs LCC guide compares the two in detail.

At the foot of each stack above the shoe or gully, directly above offsets and bends, and below hopper heads where trees overhang the roof. On tall or long runs, an extra access point part-way up makes clearance easier.
