MASC - Special expansion cone for rainwater downpipes

As roofing professionals, we know how important precise work is on site – especially when it comes to roof drainage. Anyone who has ever worked with downpipes from different manufacturers knows the problem: The pipes often differ slightly in diameter. This is where the MASC special expander cone for downpipes comes into play – a truly professional tool that no toolbox should be without.

Purpose & Sizes

The adjustable coner from MASC was specially developed to compensate for slight tolerances in pipe diameters. Due to production reasons, these often fluctuate by one to two millimeters – which can quickly lead to problems during assembly or installation. The special expanding coner enables precise and gentle expansion of the pipe ends, ensuring a perfect fit. Whether 75, 76, 80, 87, 100, or 120 mm – the coner is available in all these diameters and thus covers the common sizes in the plumbing and roofing sectors.

Three clear advantages of the MASC special expansion cone

1. Flexibility through adjustability : With a tolerance compensation option of +/- 1 mm, almost all common pipes can be machined to a precise fit – a real plus in daily use on the construction site.
2. Professional workmanship : The high-quality workmanship makes working with the tool particularly pleasant. The tool sits comfortably in the hand, is durable, and is built to withstand the rigors of everyday construction work – typical of solid roofing accessories .
3. Time savings and safety : The precise fit of the pipes not only simplifies installation but also increases leak tightness. This saves time and ensures consistently reliable results.
