Clear

The RB501COG is a side rafter rise and fall bracket for the common ogee cast iron gutter. Where there is no fascia board — on open eaves, or where the rafter face is the only available fixing point — the RB501COG mounts directly to the side face of the rafter and provides adjustable support at the correct height for the common OG gutter run. The bracket cup is shaped for the ogee S-curve profile.

The threaded rise and fall cup allows precise fall setting at each bracket position independently of the rafter pitch, eliminating shimming and packing on long runs or where the roof line is uneven. Available in three sizes to suit the standard common ogee range: 100mm (4″), 115mm (4.5″), and 125mm (5″).

Also compatible with common ogee guttering manufactured by Osma, Marley, Hunter, and Lindab, making it a practical bracket solution on mixed or partial replacement installations. Specified on listed buildings, heritage conservation projects, and period properties across England and Wales where the common ogee is the correct profile.

Compatibility: Common ogee gutter 100mm, 115mm, 125mm. Also suits Osma, Marley, Hunter, and Lindab common OG. For specification support, call 0333 987 4452.

What building types is the Brass Rooflight Hand Winder Opener – Telescopic suited to?

What building types is the Brass Rooflight Hand Winder Opener – Telescopic suited to?

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.

We are renovating a barn and would like to know what the anticipated life expectancy of your guttering and pipework would be.

We are renovating a barn and would like to know what the anticipated life expectancy of your guttering and pipework would be.

The standards for our cast iron gutters and pipes have remained remarkably constant for many years. The physical properties of cast iron are sustained throughout its lifetime thus maintaining its effectiveness. Coupled with is durability and proper maintenance, we would expect our traditional cast iron rainwater products to last for over 50 years under normal conditions.

What building types is the Pultney Tapered Hopper Head suited to?

What building types is the Pultney Tapered Hopper Head suited to?

The Pultney Tapered Hopper Head is well suited to Georgian and Regency townhouses, Victorian terraces, rural farmhouses, barns, and functional estate buildings where a plain, period-correct hopper is the appropriate specification. It also works well on new heritage-style construction. Its unfussy, chamfered form makes it a versatile choice across a wide range of traditional building types.

What building types is the Regent Cast Iron Hopper Head No.1 (H1) suited to?

What building types is the Regent Cast Iron Hopper Head No.1 (H1) suited to?

The Regent H1 is well suited to Victorian and Edwardian terraces, listed commercial buildings, civic and institutional properties, and ecclesiastical buildings where a traditional funnel-form hopper is architecturally appropriate. Its multi-faceted tapering body reads as period-accurate on Gothic and classical building types alike, and it is a commonly specified choice for conservation and listed building projects across the UK.

What building types is the Iron Works Hit & Miss Vent in Polished Brass suited to?

What building types is the Iron Works Hit & Miss Vent in Polished Brass suited to?

The Polished Brass finish suits buildings where brass metalwork was standard — formal Victorian terrace housing, civic and institutional buildings, and high-quality estate architecture. It is appropriate on listed buildings and conservation properties where the wider ironmongery specification is in brass and a matching material is required.

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.

Are cast iron airbricks suitable for use on listed buildings?

Are cast iron airbricks suitable for use on listed buildings?

Yes. Cast iron airbricks are frequently specified for listed buildings and conservation area properties precisely because they replicate the material and pattern of the original Victorian and Edwardian ventilation grilles. Local conservation officers and building control typically accept like-for-like cast iron replacements without objection. We can provide product specifications and material datasheets to support applications.

What is the difference between the Antique Black, Polished Lacquered, and Polished Brass finishes?

What is the difference between the Antique Black, Polished Lacquered, and Polished Brass finishes?

The Antique Black finish is cast iron with a blackened surface — the most historically accurate finish for cast iron ironwork and the most appropriate for the majority of heritage applications. Polished Lacquered is cast iron with a bright polished surface sealed with clear lacquer, suited to interiors and sheltered locations where polished ironwork is the specification. Polished Brass is solid polished brass throughout — the correct choice where existing building fittings are in brass or where a warm metal tone is required.

What pipe connection sizes do your cast iron hopper heads accept?

What pipe connection sizes do your cast iron hopper heads accept?

The Paxton H82 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. Bespoke adaptations including double pipe connections are also available on request. Please confirm your required connection type when ordering.

What is the Brass Rooflight Opener Handle 1520mm used for?

What is the Brass Rooflight Opener Handle 1520mm used for?

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.
