ORL-TRRF – Osma Roofline Top Rafter Rise and Fall Adjustable Gutter Bracket

£34.50 +VAT

Osma roofline top rafter rise and fall adjustable gutter bracket.  Our bespoke top rafter rise and fall gutter bracket is designed to suit the Osma Roofline system and is available with black and grey riser cups.

Osma Roofline guttering bracket, adjustable rise and fall, top rafter

Bespoke made – 10 – 14 days.

Application similar to: Osma OT147G side rafter arm

Clear

The ORL-TRRF is a bespoke top rafter-mounted rise and fall gutter bracket, manufactured to suit the Osma Roofline 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 rather than the fascia face or rafter side — typically where roof construction or access conditions make top-fixing 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 bow-and-pin gutter cup in black or grey. The adjustable riser provides full fall control along the gutter run. Compatible with the Osma Roofline 6T694 system, and designed as a functional equivalent to the Osma OT147G side rafter arm.

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 Roofline guttering.

Manufactured to order in black or grey riser cup options. Lead time 10–14 working days from order confirmation.

System compatibility: Osma Roofline half-round guttering system. Replaces Osma OT147G side rafter arm. For specification queries, call 0333 987 4452.
