All FAQ
Which Bracket Should I Use?

Which Bracket Should I Use?

We manufacture a wide variety of brackets for many different cast iron gutter and pipe profiles. More common types are the rise and fall, top fix and side fix rafter and the holderbat or pipe clip.

We can also offer traditional drive brackets, repair brackets and fascia brackets in both steel and cast iron.

It is always advisable to replace like with like because quite often the brackets form and important part of the buildings architecture. Occasionally buildings have special decorative brackets and our UK manufacturing allows us to produce small quantities of bespoke brackets when required.

Please can you advise whether we will require 1/2″ or 3/4″ BSP connections for our new cast iron radiator.

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.

What building types is the School Board Cast Iron Airbrick suited to?

What building types is the School Board Cast Iron Airbrick suited to?

The School Board Airbrick is suited to Victorian and Edwardian terraced housing, mid-century school buildings, civic halls, public baths, and converted institutional buildings. Its plain square-grid face matches the utilitarian aesthetic of late-Victorian construction and is also appropriate for new heritage-style builds in conservation areas.

Heritage colour finishes and factory-applied linseed oil paint are available on request. Linseed oil paint is a vapour-permeable, period-appropriate finish particularly well suited to listed buildings and conservation area properties.

My house has a plastic guttering system. Can I use your brackets to replace my exisiting broken ones?

My house has a plastic guttering system. Can I use your brackets to replace my exisiting broken ones?

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.
