Irwin 65104 White Chalk Refill 5 Pounds High Visibility

Product Description

The IRWIN INDUSTRIAL TOOL CO 65104 is a 5-pound white chalk refill designed for use with self-chalking reel tools. Part of the Strait-Line product line, this chalk is formulated for high visibility on a wide range of job-site surfaces. White is classified as a temporary color, meaning lines are easy to remove after layout work is complete. The proprietary formulation produces dark, sharp lines with reliable performance across applications. Chalk containers are filled by weight, not volume, ensuring consistent fill per unit.

This chalk refill suits layout and marking tasks on wood, drywall, concrete, stone, and metal. It is commonly used by carpenters, framers, concrete finishers, drywall installers, and general contractors for snapping reference lines, layout grids, and cut marks. The temporary white formula is well suited for interior work where clean removal is necessary after the task is done. It is sold in a case pack of 4 units.
