ABSTRACT:
To increase the slip resistance of level indicators, which comprise an elongate body, spirit level capsules inserted therein and protective end caps, the contact surface adjoining the measuring surface of the level indicator is provided with zones having a high coefficient of friction, for example by clipping on strips consisting of rubber, rubber like plastics material or felt. The strips are shaped to cause the body to incline so that the measuring surface is more toward the support which the contact surface faces.
