The Stratham No.513 solves a problem that comes up constantly on historic buildings and has very few good answers: what to do where a rainwater head has to sit in an internal angle.
The casting is an open square box with a boldly moulded, outward-flaring rim. Beneath it the body is deeply corbelled — a series of stepped mouldings that sweep inward and downward to the outlet, giving the underside real sculptural depth. Because the form is symmetrical about its diagonal, it sits correctly in a re-entrant corner where a conventional flat-backed hopper would leave an awkward gap or require packing out.
Internal angles are where rainwater problems concentrate on historic fabric. Two roof slopes discharge into one place, the wall is often in permanent shade, and any overflow runs directly into a junction that is difficult to inspect and expensive to repair. A hopper of adequate capacity, properly detailed for the angle, is worth far more than its cost.
The stepped underside is not only decorative. It carries the visual weight of the casting down to the pipe, so the head does not appear to float, and it gives the corbelling enough projection to throw water clear of the wall face.
Cast in solid iron to BS 460:2002 and supplied in primer or black as standard, with heritage colours and traditional linseed oil finishes available on request.
Pipe connections: 65mm, 75mm and 100mm round; 75×75mm, 100×100mm and 125×125mm square; 100×75mm, 125×100mm and 150×125mm rectangular.
Suitable for listed buildings and conservation areas. Corner locations frequently benefit from a site survey before specification is finalised — access, angle and discharge are rarely as drawn. Call 0333 987 4452 to discuss a survey or a bespoke variation.

The Gothic foliate tracery design of the Ornamental Airbrick provides a good free-flow ventilation area relative to its face size. The open area is comparable to other standard cast iron airbrick patterns. The visual density of the pattern at a distance reads as solid ironwork, which suits formal and decorative elevations without compromising subfloor ventilation effectiveness.
The H527 measures 430mm wide x 195mm deep x 540mm high, making it well suited to Victorian villas and townhouses where a decorative leader head is wanted.
The Strayton H42A accepts round, square, and rectangular pipe connections. Round: 65mm, 75mm, and 100mm. Square: 75×75mm, 100×100mm, and 125×125mm. Rectangular: 100×75mm, 125×100mm, and 150×100mm. Please specify your required connection size when ordering.
Our hopper heads are available with a wide range of pipe connections to suit round, square, and rectangular downpipes. The Calnethorpe No.11 accepts round 65mm, 75mm, and 100mm; square 75×75mm, 100×100mm, and 125×125mm; and rectangular 100×75mm, 125×100mm, and 150×100mm.

Yes. Bespoke copy casting is a core service at Tuscan Foundry Products. We can replicate any cast iron gutter, downpipe, hopper head, or fitting from drawings, detailed photographs, or a physical sample or surviving section. Each commission is assessed individually. Lead time is typically 12 to 14 weeks, and quantities as low as a single piece can be considered depending on pattern-making costs.
Yes. The polished chrome telescopic rooflight hand winder opener is compatible with Lumen Rooflights and most timber-framed skylights. Call 0333 987 4452 to confirm compatibility with a specific rooflight model.
The Brass Rooflight Opener Handle 1520mm is a pole-operated handle designed for manual rooflight opening mechanisms. It is suitable for use with Lumen Rooflights and compatible timber-framed skylights, and is particularly appropriate for period and heritage properties where a brass finish is specified.
Our cast iron hopper heads are available in a choice of finishes including primer, painted, and specialist heritage finishes. Please call us on 0333 987 4452 or submit an enquiry to discuss the right finish for your project.
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.
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.
