About this product
This Faithfull chalk line is a 100 metre spool of braided nylon line, used with powdered chalk to mark straight lines between two points. It suits general construction, carpentry and layout work where a reliable marking line is needed over medium to large distances. The braided construction resists fraying and offers greater strength and less stretch than conventional twisted cord, helping to keep marks accurate even over longer runs. Because it doesn't spin like twisted cord, it can also be used effectively as a plumb line.
