The OSRL-TRRF is a bespoke top rafter-mounted rise and fall gutter bracket, manufactured to suit the Wavin Osma Roundline half-round PVC guttering system. The top rafter variant is required where the fixing is to be made to the top surface of a rafter — on open eaves, cut roof constructions, or where the roof structure makes top-fixing the most practical option.

The bracket features a right-angled galvanised steel rafter plate for top-surface fixing, combined with a threaded steel riser column and a half-round bow-and-pin gutter cup compatible with the Roundline system. The adjustable riser allows fall to be set at the correct gradient along the run independently of roof pitch. Available in black or grey riser cup options.

Used on open eaves and cut roof constructions with Wavin Osma Roundline guttering, and on refurbishment projects where the existing roof structure dictates the fixing approach. Suitable for residential and light commercial applications.

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.

The standards for our cast iron gutters and pipes have remained remarkably constant for many years.

We manufacture a wide variety of brackets for many different cast iron gutter and pipe profiles. More common types are the rise and fall, top fix and side fix rafter and the holderbat or pipe clip.
