RB500 – Top Rafter Rise and Fall Bracket for Plain Half Round Gutter

£25.85 – £29.15Price range: £25.85 through £29.15 +VAT

Top rafter rise and fall bracket for half round cast iron guttering. Our zinc plated
top rafter rise and fall gutter bracket is available in the following sizes:
100mm (4″)
115mm (4.5″)
125mm (5″)
150mm (6″)

Clear

The RB500 is a zinc-plated top rafter rise and fall bracket for plain half round cast iron guttering. Where a fixed bracket is not appropriate — on open eaves, cut roof constructions, or where the rafter provides the only available fixing point — the top rafter bracket provides a secure, adjustable support mounted directly to the top surface of the rafter.

The bracket features a zinc-plated steel rafter arm for top-surface fixing, combined with a threaded rise and fall cup that allows gutter fall to be set precisely at each bracket position. Available in four sizes to suit all standard cast iron half round gutter profiles: 100mm (4″), 115mm (4.5″), 125mm (5″), and 150mm (6″).

Suited to new construction with exposed rafters, heritage restoration projects where a continuous fascia board is absent, and any situation where top rafter fixing is structurally preferred. Commonly specified alongside cast iron half round gutter sections and angle fittings on period and listed building projects where precise fall control is critical to long-term performance.

The rise and fall mechanism eliminates the need to pack or shim the bracket, allowing accurate gradient setting across long gutter runs on uneven or complex roof lines. Zinc-plated finish provides corrosion resistance for outdoor use.

Compatibility: Cast iron half round gutter profiles 100mm, 115mm, 125mm, and 150mm. For technical queries or project specification support, call 0333 987 4452.

All FAQ
What building types is the Cast Iron Louvre Airbrick suited to?

What building types is the Cast Iron Louvre Airbrick suited to?

The Cast Iron Louvre Airbrick suits Victorian, Edwardian, and inter-war residential and commercial properties where the louvre-pattern vent was the standard specification. It is the correct like-for-like replacement on listed buildings and conservation area properties, and suits new heritage-style construction requiring an authentic period ventilation grille.

What pipe connection sizes does the Pultney Tapered Hopper Head accept?

What pipe connection sizes does the Pultney Tapered Hopper Head accept?

The Pultney Tapered Hopper Head is available in three pipe connection sizes: 65mm (2.5"), 75mm (3"), and 100mm (4"). Each size connects directly to matching cast iron downpipes via spigot and socket. Compatible downpipe codes are: 65mm — RH025, XRH025; 75mm — RH03, XRH03; 100mm — RH04, XRH04.

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.

What building types is the Paxton H82 hopper head suited to?

What building types is the Paxton H82 hopper head suited to?

The Paxton H82 is a large-format hopper with decorative collar mouldings, making it particularly well suited to late Victorian and Edwardian buildings where the rainwater system forms part of the architectural composition. Typical applications include commercial heritage buildings, civic buildings, large detached houses, institutional premises, and warehouse conversions where a more substantial fitting is appropriate.

Which rooflight opener is best for a skylight above a kitchen sink or worktop?

Which rooflight opener is best for a skylight above a kitchen sink or worktop?

For rooflights directly above a worktop or sink, a telescopic screw-jack hand winder is the most practical choice. Available in polished brass, satin chrome, and polished chrome, these openers allow controlled ventilation from a fixed handle position without requiring a pole. The 150mm or 250mm size is typically appropriate for standard-height kitchen rooflights.

What building types is the Iron Works Patterned Hit & Miss Vent suited to?

What building types is the Iron Works Patterned Hit & Miss Vent suited to?

The Iron Works Patterned Hit & Miss Vent suits Victorian and Edwardian buildings where decorative cast iron or brass ventilation grilles were part of the original specification — including terrace houses, civic buildings, churches, entrance halls, and estate properties. It is appropriate on listed buildings and conservation area properties as a like-for-like decorative vent replacement, and on new heritage-quality construction where period detailing is required.

Is the polished chrome rooflight opener compatible with Lumen Rooflights?

Is the polished chrome rooflight opener compatible with Lumen Rooflights?

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.

What building types is the Cast Iron Louvre Airbrick suited to?

What building types is the Cast Iron Louvre Airbrick suited to?

The Cast Iron Louvre Airbrick suits Victorian and Edwardian terraced housing, semi-detached properties, public houses, agricultural buildings, and workshop structures where the original airbrick was a louvre-face grille.
