Extra Fluo Mass. The extra-strong, non-snagging site line.
The site line is one of those tools that must meet the highest quality standards, as it can play a crucial role—or cause serious errors—on construction sites.
The Fluo Extra Mass line was created precisely to meet all these requirements: outstanding in strength, visibility, and holding power.
Its special weave makes it non-snagging, ensuring excellent resistance to stress and exceptional tension holding: the greater the pulling force, the tighter the weave becomes.
Made with first-choice raw materials, it is available in different versions and sizes:
Ø 1 – the finest size, valued for precision work such as plumbing and brick facing; available in yellow fluo with white reflective tracer.
Ø 1.5 – the most widely used size on construction sites, ideal for indoor marking, plumbing, and reinforcement; available in yellow fluo with red tracer, and orange fluo with white reflective tracer.
Ø 2.5 – increasingly popular and in demand, ideal for foundations, reinforcements, outdoor marking, and road works; available in yellow fluo with red tracer, and orange fluo with white reflective tracer.
Ø 3.5 – chosen for its high visibility even from a distance, ideal for marking large construction sites. Available in orange fluo with white reflective tracer.
