As roofing professionals, we know how important it is to work precisely 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 precisely where the MASC Special expansion cones for rainwater downpipes come into play – a real professional tool that should be in every toolbox.
Purpose of use & sizes
The MASC's adjustable coner 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 when assembling or assembling. The special expanding cone 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 sector.
Three clear advantages of the MASC special expansion cone
- Flexibility through adjustability: With a tolerance compensation option of +/- 1 mm, almost all common pipes can be machined to a precise fit – a real advantage in daily use on the construction site.
- Professional workmanship: The high-quality workmanship makes working particularly pleasant. The tool lies well in the hand, is durable and made for the tough everyday use on the construction site – typical of solid Accessories for roofers.
- Time savings and securityThe precise fit of the pipes not only simplifies installation but also increases leak tightness. This saves time and ensures consistently reliable results.

High customer satisfaction

Sticks like hell
Rating for the sealing adhesive: Top for roof repairs!
The sealant is easy to apply, adheres perfectly, even to damp surfaces, and remains flexible after curing. Highly recommended!

Very good
I've been using the seam closer for a week now, and I have to say, it's simply fantastic: lightweight, robust, and the black rubber caps are fantastic at preventing it from slipping off quickly. Absolutely top-notch.

Friend winding core
An absolute must-have! No more flat rolls, easy to use, and the even pressure ensures a seamless seam. Will be reordering immediately!
