Products don’t always have to be complicated to achieve the best results – and Probst’s STRINGALONG String aid is the proof in the pudding.

More often than not, when installing paving stones, kerbs, slabs and bricks, straight and square lines/edges are essential, and when using conventional plumb lines, workers may catch the line against the stone therefore not giving an accurate straight line reading – but with the STRINGALONG, operators get a clearance of 4-5mm between stone and string line, giving great results every time.
