Key Features & Benefits

• Authentic Cast Iron Effect Finish: Detailed moulding and realistic surface texture deliver genuine period charm.

• High Capacity Performance: Formulated for large-bore 105mm round downpipe runs, complementing the Cascade 170mm High Capacity gutter system.

• 112.5° Offset Navigation: Ideal angle for directing downpipe runs around roof eaves, projecting brickwork, and wall offsets.

• Lightweight & Fast Installation: Simple push-fit spigot assembly drastically cuts down on labor time and site handling costs compared to cast iron.

• Maintenance-Free Durability: Non-corrodible, UV-stabilised uPVC retains its shape and finish without peeling or rusting over time.

• Fully Accredited: Manufactured in full compliance with BS EN 607:2004 and ISO 9001:2015 quality standards.

  The BR909CI 112.5° bend is designed for use in conjunction with 105mm Cascade Round Downpipes and is the recommended downpipe diameter for the Cascade 170mm High Capacity rainwater system.

  • Offset Assemblies: Combine two 112.5° bends together with a short length of 105mm downpipe to create custom swanneck offsets from the gutter outlet to the wall surface.

  • Fixing: Ensure pipes and fittings are secured using compatible Cascade 105mm Downpipe Clips placed at a maximum spacing of 1.8 metres.

  • Expansion Allowance: Always leave a 10mm thermal expansion gap when inserting downpipe ends into push-fit sockets.

Achieve an authentic, traditional heritage look with all the practical benefits of modern uPVC using the Brett Martin Cascade 105mm Cast Iron Style 112.5° Bend (BR909CI). Engineered to replicate the detailed texture, crisp architectural lines, and heavyweight appearance of real cast iron, this high-performance 112.5° downpipe bend is ideal for period restorations, traditional builds, and high-capacity commercial drainage projects.

Designed specifically as an offset directional bend, the 112.5° angle allows you to navigate overhangs, soffits, wall offsets, and architectural features cleanly, routing your 105mm round downpipe system directly back toward the brickwork face.

Made from premium architectural-grade, UV-stabilised uPVC, the Cascade range offers full weather resistance with zero risk of rust, rot, or paint flaking. Unlike genuine cast iron, it requires no heavy lifting equipment during installation and zero ongoing repainting or anti-corrosion maintenance.
