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 drop end outlet provides a downpipe connection at the end of a G46 gutter run, used where the run terminates and drainage drops to a downpipe from the end section rather than from a central nozzle outlet. The G46 moulded profile is maintained at the terminal point, completing the installation consistently on the large Victorian and Edwardian properties where this pattern is standard.
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 drop end outlet is not interchangeable with common ogee fittings.
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.
Compatibility: G46 moulded cast iron gutter 125mm and 150mm only. For specification support, call 0333 987 4452.

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.
Yes. Cast iron hopper heads are the historically correct choice for listed and period buildings, and a like-for-like cast iron replacement is generally accepted without objection by conservation officers. We manufacture to BS 460 for genuine heritage character and durability.
In most cases, replacing like-for-like cast iron guttering on a listed building does not require Listed Building Consent (LBC), provided the replacement matches the existing profile, material, and finish exactly. However, any change of material away from cast iron will almost always require consent. We recommend consulting your local conservation officer before proceeding, and we can provide specification documentation to support your application if required.

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.
