The OSRL-FRF is a bespoke fascia-mounted rise and fall gutter bracket, manufactured to suit the Wavin Osma Roundline half-round PVC guttering system. Where precise fall control is required along the gutter run — particularly on longer runs, older or irregular fascias, or where the gutter fall cannot be derived from the fascia line itself — the adjustable riser bracket allows the gutter to be set at the correct gradient at each fixing point.
The bracket features a galvanised steel fascia plate with pre-drilled fixing holes and a threaded steel riser column, topped with a half-round bow-and-pin gutter cup compatible with the Roundline system. The riser height adjusts to set fall independently of the fascia plane, without packing or shimming. Available in black or grey riser cup options to match the existing installation.
Suited to new-build and refurbishment projects using Wavin Osma Roundline guttering, and to maintenance work where fall correction is required without replacing the fascia. Used on residential and light commercial properties.
Manufactured to order in black or grey. Lead time 10–14 working days from order confirmation.
System compatibility: Wavin Osma Roundline half-round PVC guttering system. For specification queries, call 0333 987 4452.

Yes, provided they are sized for the lower water temperature. Outputs are published at ΔT50; at ΔT30 a section gives about half that, so heat pump systems usually need more sections or a deeper pattern. We can prepare a radiator schedule at your heat pump design temperature.
Hopper heads are supplied in red oxide primer ready for on-site painting, or pre-finished in black. A full range of Heritage Colours in traditional linseed oil paint is also available on request — please contact us for the swatch chart.
A hit and miss vent has a sliding plate on the reverse of the grille that can be moved to open or close the ventilation apertures. This allows airflow to be regulated without removing or replacing the grille. The vent can be fully open, partially open, or fully closed depending on ventilation requirements.

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.
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.
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.
