Irwin Strait-Line white standard marking chalk delivers high-visibility, temporary lines for layout work on the jobsite. The weather-resistant formula works indoors and outdoors and marks cleanly on a wide range of surfaces including wood, drywall, concrete, stone, and metal. A flip-top cap seals the chalk in an airtight chamber to keep out moisture and reduce clumping, and the marks remain temporary for easy removal and adjustment. Supplied in a 4 lb refill container for use with standard chalk reels.
