GN2279-ALN-20-K-30-B Bulls Eye Level, J.W. Winco, Mfr#: GN2279

GN 2279 bull's eye levels are used to check the horizontal position of jigs, machines, devices, appliances and instruments. Type A is suggested 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 surface so that the bubble is centrally located inside the marking ring when the horizontal position of the contact surface is achieved.
