Starrett No.98 Series Machinists' Level

These levels have ground and graduated main vials. The vials are adjustable to a positive setting and are housed in a satin finished brass tube with a friction-fit closing cover to prevent breakage. The base of the level features an involute groove running the length of the base, which provides a reliable seat for round work such as pipes or shafting. The cross test vial prevents inaccuracies in the main vial reading caused by canting the level sideways on round work.
