The Spear and Jackson Cosmos Chalk Line is a reliable marking tool designed for accurately snapping straight lines across timber, masonry, flooring, and other building surfaces. Built around a durable ABS plastic case, this chalk line is constructed to withstand the demands of everyday use on site. The 30m double twisted poly cotton line provides ample reach for a wide range of marking tasks, from setting out stud walls to laying floor coverings and marking roofing materials. A rapid 4 to 1 rewind ratio means the line can be retrieved quickly between uses, keeping work moving at pace. The nickel steel handle locks in one position, giving a secure, comfortable grip when pulling the line taut for precise, repeatable marks.
