Circular spirit level for mounting

Bull´s eye spirit levels GN 2279 are used to check the horizontal position of jigs, machines, devices, appliances and instruments. Type A is used if the spirit level is to be used as a tool, e.g. at different measuring points. The spirit levels are aligned in relation to the reference or contact surface, such that the bubble is located inside the marking ring once the horizontal position of the contact surface is reached.
