Exceptionally stable and accurate with easy-reading vernier style. Long, 50-division vernier scales permit half as many graduations as single vernier tools. Widely spaced graduations make easy reading to .001" or 0.02mm without needing a magnifying glass. Flush fitting of the vernier scale to the main scale means that these are in the same plane, which eliminates parallax. Extremely fine adjustments are achieved by a knob located on the base. Quick-adjust release on the slide allows for fast positioning. Special master bar design and the balanced design and weight of the base eliminates vibration. Vertical bar is positioned near the center of the base for balance and stability. Versatile tool will scribe lines, mount dial indicators or electronic probes and accept depth attachments. Base is hardened, ground and lapped square. Fitted Case, Scriber.
