Strait-line 5 Lb. Red Permanent Chalk Line Chalk

Irwin Strait-Line Red Marking Chalk Refill is a professional-grade marking chalk designed for contractors, construction workers, and commercial users who need permanent, visible marks on job sites. This 5-pound refill bottle delivers vivid red markings that remain visible even after weeks of weather exposure and jobsite wear, making it ideal for both interior and exterior use.

The chalk is odorless, making it suitable for indoor applications without unpleasant fumes. The newly engineered flip-top cap keeps chalk contained in the bottle and stops it from spilling into work areas where it is not needed. The secure closure seals the chalk in an air-tight chamber, keeping out moisture and significantly reducing the risk of clumping, which extends the product's shelf life and ensures consistent performance over time.
