MASC - Special expansion tool for rainwater downpipes

Precise fit for every pipe connection - professional quality for roofers & sheet metalworkers

As a roofing professional, one thing matters above all: connections must fit. With rainwater downpipes in particular, pipes from different manufacturers often have slightly different diameters. This can make installation on the gutter unnecessarily difficult - or, in the worst case, lead to leaks. That is exactly what the MASC special expansion tool for rainwater downpipes is designed for: You adjust pipe ends precisely without damaging the material - quickly, in a controlled manner, and cleanly.

Specialist use in roof drainage

The expansion tool is used to precisely flare or expand the end of a rainwater downpipe, so that the next pipe section can be inserted cleanly. It is particularly useful for tolerances of 1–2 mm, repairs to existing installations, or when combining different systems. You work in a controlled manner and achieve even expansion - for a watertight, stable push-fit connection in everyday sheet metal and roofing work. In combination with suitable roofing tools and sheet metalworking tools, installation becomes significantly more efficient.

Practical tip: prepare carefully
