Clear

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.
