Crescent Lufkin CB08BL 8 oz Black Chalk Refill Bottle Permanent Marking Dust for Construction Line Reels Layout

High-Contrast Permanent Marking for Professional Layouts

Ensure your layout lines remain visible in the toughest job site conditions with the Crescent Lufkin CB08BL 8 oz. Black Chalk Refill. Designed for professional tradespersons who require reliability and precision, this marking dust provides a bold, high-contrast line that stands out clearly on concrete, roofing, and other light-colored surfaces. Unlike standard temporary chalks, black chalk is typically formulated for permanence, making it the ideal choice for exterior framing, foundation work, and long-term layout applications where rain and foot traffic might erase lighter markings.

Crescent Lufkin has engineered the packaging with the user in mind to maximize efficiency on the job. The bottle features a unique non-roll geometry, ensuring that if you set it down on a sloped roof or uneven concrete slab, it stays exactly where you put it. Additionally, the easy-fill nozzle design promotes a smooth, fast flow of powder, allowing you to refill your chalk reel quickly without the messy clumping often associated with inferior products. Compatible with all standard chalk reels, this 8-ounce bottle delivers the performance and durability needed for professional construction environments.

Specifications

Pro-Tip: Black chalk is generally considered permanent. Use it for exterior layout, concrete work, or roofing where you need the line to survive the elements. Avoid using black chalk on interior carpeting or finished walls that will be painted with light colors, as it can be very difficult to clean or cover.
