255-12 Vernier Height Gage 51230

The Starrett 255 is the "baby brother" of the 254 Master Vernier Height Gage. It is essentially the same tool, but a much lighter version for normal use where heavy duty applications are not practical. 0-12” Range, .001” Grad without Case.

  • Black lines and figures against Starrett satin chrome finish make reading easy
  • Scriber and base are designed for direct reading from zero (bottom of base)
  • Quick-adjust release on the slide allows for fast positioning
  • Extremely fine adjustments by a knob on the base isolating the column and slide from external pressures
  • Additional remote fine adjustment located on top of the bar for sizes 36 (900mm) and larger
  • Special master bar design and the balanced design and weight of the base eliminates vibration
