MASC – Special expansion cone for rainwater downpipes

Precise fit for every pipe connection – professional quality for roofers and plumbers

As a professional roofer, one thing is paramount: connections must be secure. Especially with downpipes, it's common for pipes from different manufacturers to have slightly different diameters . This can unnecessarily complicate installation on the gutter – or, in the worst case, lead to leaks. That's precisely what the MASC special expansion cone for downpipes is designed for: it allows you to precisely adjust pipe ends without damaging the material – quickly, accurately, and cleanly.

Specialized use in roof drainage

The expansion cone is used to precisely flare or expand the end of a downpipe so that the next pipe section can be inserted cleanly. This is particularly useful for tolerances of 1–2 mm, for repairs on existing systems, or when mixing different systems. You work with control and achieve a uniform expansion – for a tight, stable connection in everyday roofing and plumbing work. When combined with suitable roofing and plumbing tools, installation becomes significantly more efficient.
