This Spear and Jackson Chalk Line Refill is supplied in red, making it ideal for marking on lighter-coloured surfaces where a bold, high-visibility line is needed. Red chalk offers strong contrast on pale materials such as timber, plasterboard, and concrete, helping to ensure your marks are clear and easy to follow throughout a job. The refill bottle comes in a unique hanging pack with euroslot, so it’s easy to keep organised on your workbench or in storage. It screws directly onto Roadline cases for a clean, mess-free refill, or can be used to top up from the tip when a quick top-up is all that’s required. Features and Benefits: • High-quality chalk for precise, clean line marking • Unique hanging pack with euroslot refill bottle • Compatible with all Spear and Jackson chalk lines • Screws directly onto Roadline cases for easy, mess-free refilling • Can be used to refill from the tip
