The OSL-TRRF is a bespoke top rafter-mounted rise and fall gutter bracket, manufactured to suit the Osma SuperLine half-round PVC guttering system. The top rafter bracket is the appropriate fixing solution where the bracket needs to be secured to the top surface of a rafter — typically on open eaves, cut roof constructions, or where top-fixing is the most practical or structurally sound option.
The bracket features a right-angled galvanised steel rafter plate for top-surface fixing, combined with a threaded steel riser column and a bow-and-pin gutter cup in black. The adjustable riser provides full fall control along the gutter run independently of the roof pitch. Compatible with the Osma SuperLine guttering system.
Used on open eaves and cut roof constructions where top rafter access is available and preferred, and on refurbishment projects where the existing roof structure dictates the fixing method. Suits both residential and light commercial applications 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 Ornamental Airbrick is most appropriate on Victorian Gothic buildings — churches, chapels, vicarages, almshouses, collegiate buildings, and high-specification estate architecture — where decorative ironwork was part of the original design. It suits listed building replacements in kind and heritage new build where period accuracy in detailing is expected.
Our cast iron hopper heads are available with 65mm, 75mm and 100mm round outlets, 75mm, 100mm and 125mm square outlets, and 100x75mm, 125x100mm and 150x125mm rectangular outlets, to match the downpipe already on site or specified for the project.
The H1A is available with round pipe connections in 65mm, 75mm, 100mm, and 150mm diameters. Please specify your required connection size when ordering, as this determines the SKU. If you are unsure of the correct pipe size for your project, our team can advise — call 0333 987 4452.

It is compatible with Lumen Rooflights and most timber-framed skylights.
