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.

The Rectangular Pipe to Round Connector changes a rectangular downpipe to a round section, for connection to a round pipe, a round gully inlet or an underground drain socket.
It is used at the foot of a run where the below-ground drainage takes a round pipe, or where a rectangular run must join an existing round system.
Round outlets are 65mm, 75mm or 100mm. The 100mm round outlet is not made for 125mm x 70mm pipe.
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.

All of our cast iron radiators are availbale as standard with a 1/2″ BSP (15mm) connection. We are though also able to supply many of our radiators and valves with 3/4″ BSP connections. Due to the size proportions of some radiators and valves 3/4″ connections may be more suitable.
The Polished Lacquered finish suits buildings where period ironwork was finished bright rather than painted — formal entrance elevations, listed properties, and settings where the grille contributes to the decorative programme of the facade. It is appropriate for conservation specifications and high-specification heritage new build.
Yes, provided they are sized for the lower water temperature. Outputs are published at ΔT50; at ΔT30 a section gives about half that, so heat pump systems usually need more sections or a deeper pattern. We can prepare a radiator schedule at your heat pump design temperature.
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.
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.
Available in two sizes: 225mm x 82mm (single airbrick course height) and 225mm x 150mm (double course height). Both sizes fit standard brick coursing positions and install flush into the wall face.

All are designed for timber-framed rooflights and skylights.
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.
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.
