Overview of all MASC system variants and components

To ensure you are perfectly equipped for every gutter and every construction site size, the MASC system is available in the following versions and individual components:

2. MASC Gutter Seam Clamp 28 (Art.-No. RNZ28)

• The solution for standard gutters: Identical in construction to the large version, but perfectly adapted to 28mm gutters (7-piece). Also high-quality nickel-plated and equipped with a movable jaw for maximum precision.

3. MASC Gutter Seam Set (Art.-No. RNS)

• The practical combi-package: Ideal for quick entry or smaller projects. The set contains 1 roll of Nanofil seam insert (6 m) and 200 pieces of the matching stainless steel sealing rivets (3.2 mm).

4. MASC Nanofil Seam Insert (Art.-No. NE)

• The core of the seal: A 25 mm wide sealing insert on a 6-meter roll. The ready-to-use, non-reactive material remains permanently elastic, age-resistant and self-welding for decades.

5. MASC Sealing Rivets (Art.-No. DNE32)

• For mechanical hold: High-strength rivets made of stainless steel (3.2 mm) in a practical pack of 200. They ensure the permanent contact pressure of the gutter connection through the sealing insert.

✔ Immediate function without cooling or drying times
✔ Enormous cost savings due to reduced working time on the construction site 

Versatile & environmentally friendly for every project

The Nanofil seam insert is a true all-rounder for plumbing supplies:

• Material compatibility: Excellent compatibility with most metallic building materials and materials.
• Resistance: Absolutely age-resistant, weather-resistant, UV-resistant, water- and steam-proof, as well as dimensionally stable and solvent-free.
• Sustainability: Physiologically harmless, environmentally friendly and practically unlimited shelf life.

Ideally suited for:

• Semi-circular metal gutters in new construction & old building renovation.
• Secure gutter connections in snowy or windy regions.

Application & professional tip for the construction site

Correct application:

1. Stick the Nanofil insert to the inside of the cleaned gutter, peel off the cover strip and join the gutters together.
2. Pre-tension the seam securely with the silver MASC gutter seam clamp.

If the gutter is clearly visible, place the seam directly in the support area and set the rivets close to the gutter support. When using the gutter seam clamp, only attach or push on the gutter support after the seam has been fully formed. For a flawless finish, the rivets can then be treated with a suitable touch-up pen.
