Selected knot-free beech and hornbeam logs are specially sawed and dried in our the manufacturer’s facilities. The careful processing guarantees top quality and the highest precision down to the tiniest detail. The environmentally friendly and scratch-proof lacquers were specially developed for our dip system in over one thousand tests. The measurement gradations and the promotional printing are printed in very sharp quality and they are easily readable because of the smooth matt-gloss surface.That is why, for example, the spring fitting in the folding ruler joint cannot shift and the joint cannot loosen. So the riveted folding rulers retain their precision even after long use and in conditions of extreme dampness or dryness.
