Zinc plated coach screws in packs of 10.
UK delivery from £30. Fittings are despatched boxed. See delivery rates.
The coach screw is a heavy-duty zinc-plated wood screw used to fix cast iron downpipe strap brackets and holderbats to timber — typically to rafter feet, roof boarding, timber-framed walls, or wooden soffits where a standard masonry fixing is not available or appropriate. The coarse thread and hexagonal head of the coach screw provide high pull-out resistance in timber and allow the fixing to be driven and tightened with a spanner or socket wrench rather than a screwdriver.
Supplied in packs of 10. Zinc-plated for outdoor corrosion resistance. Appropriate for use with cast iron downpipe brackets on period buildings where timber construction is the available fixing substrate. For specification support, call 0333 987 4452.

The H1A is available with round pipe connections in 65mm, 75mm, 100mm, and 150mm diameters. Please specify your required connection size when ordering, as this determines the SKU. If you are unsure of the correct pipe size for your project, our team can advise — call 0333 987 4452.
Bespoke and copy cast iron rainwater goods typically have a lead time of 12 to 14 weeks from order confirmation. This covers pattern-making, casting, finishing, and quality inspection. Stock items are typically despatched within 5 to 7 working days, and non-stock standard profiles within 7 to 10 working days. We always recommend confirming lead times at enquiry stage so your project programme is not affected.
The H532 measures 560mm wide x 290mm deep x 305mm high, making it well suited to a broad, low-profile design suited to substantial roofs and box gutters on period commercial and civic buildings.
The opener is designed for use with Lumen Rooflights and compatible timber-framed skylights. The telescopic shaft and adjustable mounting bracket allow it to be fitted to a range of rooflight frames. If you have a specific rooflight model, call us on 0333 987 4452 to confirm compatibility.
This opener is particularly well suited to period and heritage properties — Georgian and Victorian terraces, conservation area houses, traditional orangeries, and listed buildings where a brass finish is required to complement existing ironmongery. It is compatible with Lumen Rooflights and most timber-framed 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.
Our brackets are more commonly used on cast iron rainwater systems. Unlike plastic, cast iron is heavy and the weight keeps the gutter in position. As such our brackets do not normally have retaining clips which could lead to plastic or lightweight gutters blowing out of the bracket. The profile of your gutter should match that of our bracket but without the weight to keep it in place you may well encounter problems in bad weather.
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.
The Ornamental Airbrick (OAB) is available in three sizes: 225mm × 75mm (2.8kg), 225mm × 150mm (4.1kg), and 225mm × 225mm (5.8kg). All sizes have a uniform depth of 75mm, making them consistent to install across a subfloor ventilation course.
