OX 40-ounce/2.5-Pound Standard Blue Marking Chalk - Permanence 1 OX-P630808
Product Code / SKU: 198973
The OX Pro Series 1.1kg/2.5lbs Standard Blue Marking Chalk is designed for easy professional chalk reels. Its large 2.5-pound capacity makes it ideal for bigger projects, ensuring you have plenty of chalk for extended tasks. The high-flow nozzle allows for smooth, consistent application, while the leak-proof quarter-turn twist cap seals the chalk in an airtight chamber to keep moisture out and prevent clumping.
The micro-fine formula delivers crisp, high-visibility lines, perfect for both indoor and outdoor use. Whether you’re working on wood, plasterboard, concrete, stone, or metal, this chalk provides clear, temporary lines that can easily be wiped away from smooth surfaces like drywall. It's particularly well-suited for interior jobs where marks need to be removed cleanly after use, such as marking walls, trim, or layout lines.
With a 1-day weatherability and permanence rating of 1, this chalk is durable enough for short-term marking but disappears when it’s no longer needed. Compatible with all OX chalk line reels, it offers versatility and performance for framing, carpentry, masonry, and general layout work. Trust the OX Pro Series for accurate, easy-to-remove markings, and mess-free application on every project.
