The OSL-SRRF is a bespoke side rafter-mounted rise and fall gutter bracket, manufactured to suit the Osma SuperLine half-round PVC guttering system. Where there is no fascia board — or where the rafter face is the structurally preferred fixing point — the side rafter bracket provides a secure, adjustable support for the gutter run.
The bracket features a galvanised steel rafter arm with pre-drilled fixing holes for attachment to the side face of a rafter or verge board, combined with a threaded steel riser column and bow-and-pin gutter cup in black. The adjustable riser allows fall to be set accurately at each bracket position along the run, independently of rafter pitch or line. Compatible with the Osma SuperLine guttering system.
Suited to open eaves construction, roof structures without a continuous fascia, and situations where rafter-face fixing is structurally preferable. Used on both new-build and refurbishment projects with Osma SuperLine guttering.
Manufactured to order with black riser cups. Lead time 10–14 working days from order confirmation.
System compatibility: Osma SuperLine half-round guttering system. For specification queries, call 0333 987 4452.

The Antique Black finish suits Victorian, Edwardian, and inter-war buildings where ventilation ironwork was painted rather than polished — estate houses, terrace housing, civic buildings, and rural properties. It is also correct for listed buildings and conservation area properties requiring like-for-like replacement of original ornamental cast iron vents.
Traditional Express can be painted, including in our linseed oil finish. LCC is supplied with a black bitumen coating, which cannot be reliably overpainted with conventional paints; maintain it with a compatible bituminous paint. Where a painted soil stack is required, specify Traditional Express.
Yes. Cast iron ornamental vents in period patterns are frequently specified on listed buildings and conservation area properties as like-for-like replacements for original Victorian ironwork. Conservation officers generally accept cast iron in period patterns without objection. We can supply specifications to support planning and listed building consent applications.
Our brackets are more commonly used on cast iron rainwater systems. Unlike plastic, cast iron is heavy and the weight keeps the gutter in position. As such our brackets do not normally have retaining clips which could lead to plastic or lightweight gutters blowing out of the bracket. The profile of your gutter should match that of our bracket but without the weight to keep it in place you may well encounter problems in bad weather.

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.
The Ornamental Airbrick (OAB) is available in three sizes: 225mm × 75mm (2.8kg), 225mm × 150mm (4.1kg), and 225mm × 225mm (5.8kg). All sizes have a uniform depth of 75mm, making them consistent to install across a subfloor ventilation course.
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.
The in-house Premier Extra coating is formulated for a life expectancy of around 10 years under normal weather conditions, provided any impact damage or surface scuffing is made good promptly. Coastal locations or higher pollution levels can shorten this, so it's worth asking your local stockist or paint manufacturer for site-specific advice.
