In steel construction you often need two free hands. Therefore a spirit level with rare earth magnets is a must for optimal adhesion. This model with a milled measuring surface and V-groove is characterised by strong adhesion on metallic and especially on rounded surfaces. The spirit level has horizontal spirit levels for inclinations of 1% and 2%, a vertical spirit level and a 45° angle spirit level. Practical, precise, pleasant to use and robust - a typical STABILA.
