The layout tool that gives you a clean, straight line every time across any surface on site.

The OX Heavy Duty Chalk Line is built for tradespeople who need accurate, repeatable layout marks without the mess or frustration of a cheap chalk line. The robust casing handles the knocks and drops of daily site use, and the smooth retraction mechanism keeps the line feeding and rewinding cleanly without snagging or jamming mid-job.

Supplied with high-quality blue chalk, the line snaps a clear, visible mark on timber, drywall, concrete, and most other common surfaces without leaving a cloud of dust or an inconsistent smear. Whether you are setting out stud walls, marking cut lines across sheet material, or laying out footings, this chalk line gives you the straight reference you need to work quickly and accurately.
