Perfect measurement of internal and external dimensions: Woodpeckers Big Calipers
Now, you can transfer critical dimensions with precise physical reference. A dual-function nut secure the jaws, ensuring a firm grip and perfectly aligning the jaw with the blade. This prevents any slipping or wobbling when transferring critical dimensions. The fixed jaw is locked precisely at zero, allowing you to slide the adjustable jaw out of the way and use BigCal as a T-square.
