TLV646 - Starrett 100ft High-Speed Chalk Line Reel

Precision Layout with the Starrett 100' Chalk Line

The Starrett TLV646 Chalk Line is a professional-grade layout tool designed to meet the rigorous demands of industrial construction, carpentry, and facility maintenance. When precision and speed are paramount, this 100-foot (30-meter) chalk reel delivers exceptional performance. Manufactured by Starrett, a brand synonymous with precision tools, this chalk line is engineered to provide accurate, straight markings over long distances, ensuring that your layout work is foundational to a successful project.

One of the standout features of this model is its high-speed 1:6 rewind ratio. Unlike standard chalk lines that require tedious winding, the Starrett TLV646 allows users to retract the full 100 feet of line quickly and effortlessly, significantly reducing downtime between snaps. This feature is particularly beneficial for professionals who need to make multiple layout marks in a short period. The mechanism is smooth and reliable, preventing jams and tangles that often plague lesser quality reels.

Durability is a core component of the design. The unit is housed in a high impact-resistant case featuring a rugged overmold. This construction protects the internal mechanism from drops, knocks, and the general wear and tear of a busy job site. The ergonomic shape fits comfortably in the hand, providing a secure grip even in dusty or gloved conditions. Additionally, the reel holds a generous 4 ounces of chalk, minimizing the frequency of refills and keeping you productive for longer stretches.

The tool is equipped with a stainless steel hook, which offers excellent resistance to rust and corrosion—a vital feature for outdoor work or humid environments. The hook is designed to grab securely onto edges, nails, or other anchor points, allowing for solo operation when necessary. Whether you are laying out walls, marking flooring, or defining cut lines, the Starrett 100' Chalk Line provides the reliability and efficiency required for professional results. Please note that chalk is sold separately, allowing you to choose the specific color and permanence level suited to your application.
