MARSHALLTOWN ML613 Masonry Line – Bonded Nylon, 500 ft, Yellow & Black (Made in USA)

Overview

The MARSHALLTOWN ML613 Masonry Line is a bonded nylon line designed to deliver reliable visibility and steady performance across masonry and archaeology tasks. The high-contrast yellow and black coloring helps you see layout marks clearly on busy job sites, whether outlining brick courses, setting reference lines, or preparing grids for excavation work. Built for practical daily use, this line emphasizes consistency without sacrificing flexibility when you reposition it along rough or damp surfaces.

Durability is at the core of the ML613 design. The bonded construction strengthens the line’s core, while the nylon fiber provides a balance of strength and pliability. This combination aims to maintain straight lines through the typical wear and environmental changes found on construction sites, from moist mornings to dusty afternoons. The result is a dependable tool for professionals who value clear reference points and repeatable results in real-world conditions.

Why choose the ML613 line?

The line family includes key variants that address common site needs. Braided lines offer enhanced abrasion resistance for longer life, while twisted lines are head-set after winding to stabilize the line during setup and use. These design choices support consistent layout lines as you work across concrete, stone, or earth surfaces, helping you stay aligned with project goals without constant readjustment.

• Bonded nylon composition provides reliable performance in damp environments
• Braided construction increases durability against wear and abrasion
• Twisted, head-set design stabilizes the line after winding for steady measurements
