Snap crisp, visible layout lines fast with Irwin Strait-Line Standard Marking Chalk. Use this blue marking chalk for high contrast indoors and out, then clean it off when the layout changes. Refill your chalk line box in seconds with the quick-pour squeeze bottle, and keep the crew moving. The compact 8 oz size rides easily in your pouch but delivers plenty of snaps across framing and concrete work.
