Maximum Tension & Visibility in Any Weather

The MASC special gutter line is the further development of the classic chalk line for sheet-metal workers, roofers, and carpenters. Thanks to a newly developed, specially woven core insert, this line does not absorb moisture - sagging or subsequent stretching in rain or high humidity is therefore ruled out.

Its tightly braided, extremely tear-resistant structure withstands the highest tensile loads and guarantees perfectly straight alignment when installing gutters, roof coverings, and façades.

Perfect Color Options for Every Construction Site

• Signal red/orange (item no. SRSO): Ideal for dark surfaces such as coverings with dark roof tiles, slate, or bitumen membrane.
• Signal green (item no. SRSG): Provides maximum contrast on bright, metallic surfaces such as titanium zinc, copper, or aluminum.
• Visible at dusk: The bright colors ensure excellent visibility even in difficult lighting conditions during the early morning or late evening hours.

How It Compares

Recommended Applications

• Aligning gutter brackets during gutter installation
• Aligning rows of roof tiles during installation, especially on dark surfaces such as dark roof tiles, slate, or bitumen membrane (signal red/orange variant)
• Alignment work on bright, metallic surfaces such as titanium zinc, copper, or aluminum (signal green variant)
• Precision work in façade and timber construction over long alignment runs
• Use during the early morning or late evening thanks to good visibility at dusk

Why the MASC Special Gutter Line Belongs in Your Product Range

The decisive advantage lies in its absolute dimensional and tension stability. Where conventional lines become slack when wet and need to be readjusted, the MASC special gutter line remains taut and perfectly straight. This saves rework time and prevents measurement errors on the roof.
