The String Height Gauge with Rail employs a rail to minimize keybed-benchtop discrepancy errors (with a thumb nut that spins down in the middle to prevent deflection during use). This assembly is included in both the Regulation Station Deluxe and the Regulation Station Full Monte. Up to 10 sample string heights can be recorded through vertically distinct registration holes onto an aluminum plunger. Includes:

• Automatic Center Punch
• Black Sharpie Ultra Fine Pen
