A genuine cast iron rainwater pattern the G46 or No.46 is available in two profile sizes. The profile is a larger version of the more traditional ogee (OG) curved pattern and offers increased capacity.
The cast iron G46 moulded gutter stop end closes the open end of a G46 gutter run. The full moulded section is maintained through the stop end, completing the run neatly at a gable end, chimney return, or other point of termination on the large Victorian and Edwardian properties where the G46 is the standard profile.
Manufactured in solid cast iron to BS 460:2002. Available in both G46 profile sizes: 125mm (5″) and 150mm (6″). Supplied in primed or factory black finish. The G46 stop end is not interchangeable with common ogee fittings — always specify the correct G46 stop end to ensure profile match.
Specified on listed buildings and heritage restoration projects where the G46 moulded pattern is the historically correct profile. Accepted by conservation officers as the appropriate fitting for period rainwater work on substantial Victorian, Edwardian, and later period buildings.
Compatibility: G46 moulded cast iron gutter 125mm and 150mm only. For specification support, call 0333 987 4452.

The H527 measures 430mm wide x 195mm deep x 540mm high, making it well suited to Victorian villas and townhouses where a decorative leader head is wanted.
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.
The Ornamental Airbrick is suited to Victorian villas, bay-fronted terraces, Gothic Revival institutional buildings, church halls, and civic buildings where decorative ironwork is part of the architectural language. It is also appropriate for listed buildings and conservation area properties where the airbrick is on a prominent elevation and the ventilation grille is expected to carry decorative character.
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.

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.
