Similar to a chalk line, an ink line is used to mark straight lines to wooden components. A fine silk thread is drawn out through ink soaked cotton wool, tensioned and then snapped against the workpiece. This allows you to mark very long (up to 10 m), fine and exceptionally accurate lines, also on uneven workpieces such as round timber. Can also be used as a plumb line. Unbreakable plastic body, leak-proof, auto-rewind thread. Ink not included. Comes with operating instructions. 180 x 80 x 40 mm.
