ABSTRACT:
The present spirit level has an elongated body with a longitudinal leveling face and at least one inclination peg retractably mounted in the body. The inclination peg is configured to selectably extend at least partially out from the leveling face by at least one predetermined stepwise increment, such that when it contacts a surface to be leveled, the inclination peg raises the leveling face to a predetermined angle of inclination from the surface to be leveled.
