A height gauge is indispensable in the shop for setting the projection of table saw blades and router bits, and setting jointer knives. It can also be used for measuring thickness when used on a known flat surface (such as our granite surface plate).
This gauge functions in the same manner as a caliper, where one "jaw" is the surface upon which the gauge sits. It has an easy-to-read dial face that is graduated in thousandths of an inch.
A fine-adjustment screw lets you lock and adjust the head slowly.
Unit is 11" in total height with 6" range of measurement.
