About this item

IRWIN® Strait‑Line™ 64901 – 8 oz Blue Standard Marking Chalk

Upgrade your marking accuracy with the IRWIN® Strait‑Line™ 64901 Blue Standard Marking Chalk—an essential for professionals and DIY users who need clean, visible lines on a variety of jobsite surfaces. Engineered for interior and exterior use, this high‑quality standard‑grade chalk delivers bold, easy‑to‑see markings that hold up long enough for cutting, layout, or installation work, yet fade naturally over time for minimal cleanup.

Housed in a durable squeeze bottle with an innovative flip‑top cap, this 8‑oz refill is designed to reduce clumping, control moisture exposure, and provide consistent chalk flow. Whether you're framing walls, laying out flooring, marking masonry, or aligning materials, this chalk offers reliable performance and visibility with every snap of the line.
