Clear

The RB500DH is a zinc-plated top rafter rise and fall bracket for plain deep half round cast iron guttering. Where open eaves construction or the absence of a fascia board requires fixing directly to the top surface of a rafter, the RB500DH provides a secure and adjustable support that allows precise fall setting along the gutter run.

The bracket features a zinc-plated steel rafter arm designed for top-surface rafter fixing, combined with a threaded rise and fall cup that adjusts the gutter height at each bracket position independently of the rafter pitch. Available in four sizes to suit all standard deep half round gutter profiles: 100mm (4″), 115mm (4.5″), 125mm (5″), and 150mm (6″).

Commonly specified on listed building and heritage restoration projects involving deep half round cast iron guttering, and on new construction where exposed rafters and open eaves are a feature of the design. The rise and fall mechanism eliminates the need to pack or shim the bracket, allowing accurate gradient setting across long gutter runs or on complex roof lines.

Zinc-plated finish provides corrosion resistance for outdoor use. The RB500DH is the deep half round equivalent of the RB500 bracket, dimensioned specifically for the wider and deeper profile of the deep half round section.

Compatibility: Plain deep half round cast iron gutter profiles 100mm, 115mm, 125mm, and 150mm. For project specification, call 0333 987 4452.

All FAQ
How does a hit and miss vent work?

How does a hit and miss vent work?

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.

How does the ornamental pattern affect ventilation performance?

How does the ornamental pattern affect ventilation performance?

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.

What finishes are available on your cast iron hopper heads?

What finishes are available on your cast iron hopper heads?

Our cast iron hopper heads are available in a standard primed and black-painted finish, ready for on-site topcoats. 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.

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

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.

Do you sell or make ogee guttering as we have a round double bay turrett style roof to our victorian house.

Do you sell or make ogee guttering as we have a round double bay turrett style roof to our victorian house.

We do offer a range of Ogee patterned gutters in both straight and radius profiles. The straight profiles are much more common and as such cost less.

What finish options are available for rooflight opener handles?

What finish options are available for rooflight opener handles?

Is a chrome rooflight opener compatible with Lumen Rooflights?

Is a chrome rooflight opener compatible with Lumen Rooflights?

Yes. Both the satin and polished chrome telescopic rooflight hand winder openers are compatible with Lumen Rooflights and most timber-framed skylights. Call 0333 987 4452 if you need to confirm compatibility with a specific model.

Is a cast iron hopper head suitable for use on a listed building?

Is a cast iron hopper head suitable for use on a listed building?

Yes. Cast iron hopper heads are the historically appropriate choice for listed buildings, and are generally preferred by conservation officers and local planning authorities over modern plastic alternatives. Tuscan Foundry cast iron hopper heads are manufactured in solid grey iron and are suitable for use on listed buildings and within conservation areas. A linseed oil finish is also available, which is particularly appropriate for sensitive heritage projects.

We have just purchased some cast iron radiators and they have a slightly uneven texture to the surface. What can we do about this.

We have just purchased some cast iron radiators and they have a slightly uneven texture to the surface. What can we do about this.

Casting of iron is an imperfect processs. It is possible with some cast iron radiators that you will get minor imperfections in the surface finish. When radiators are painted this will reduce and over the years every additional coat of paint applied will provide a smoother more equal finish.

What sizes and weights are available for the Ornamental Airbrick?

What sizes and weights are available for the Ornamental Airbrick?

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.
