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.

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 H460 is well suited to Georgian, Regency, and Victorian buildings where a plain, undecorated rectangular hopper is the appropriate choice — particularly listed properties, conservation area buildings, and institutional or commercial buildings in historic town centres. Its clean, restrained form makes it equally appropriate on modern heritage-style construction where period accuracy is required without ornamental detail.

Yes. Cast iron airbricks are frequently specified for listed buildings and conservation area properties precisely because they replicate the material and pattern of the original Victorian and Edwardian ventilation grilles. Local conservation officers and building control typically accept like-for-like cast iron replacements without objection. We can provide product specifications and material datasheets to support applications.
Yes. Churches and ecclesiastical buildings are one of our most common project types. We regularly supply large sand cast gutters, rectangular and square downpipes, and bespoke hopper heads for church restorations. Many churches have non-standard profiles that require copy casting. We work directly with architects, church fabric advisors, and quinquennial inspection surveyors. Historic England and many Diocesan Advisory Committees specify cast iron as the appropriate material for listed ecclesiastical buildings.

The Ornamental Airbrick is suited to Victorian villas, bay-fronted terraces, Gothic Revival institutional buildings, church halls, and civic buildings where decorative ironwork is part of the architectural language. It is also appropriate for listed buildings and conservation area properties where the airbrick is on a prominent elevation and the ventilation grille is expected to carry decorative character.
The louvre face provides directional airflow and offers some resistance to driven rain entering the subfloor void, making it a practical choice for exposed elevations or properties in areas with significant prevailing wind and rainfall. The square-grid (school board) pattern offers a larger open ventilation area but less weather protection.
