Granite Surface Plates

Granite Surface Plates


Granite Surface Plates are used to support many different types of test pieces and have the dual purpose of also providing an excellent datum from which to begin a series of measurements with an instrument like a height gage.

A used or import surface plate can compromise the accuracy of your part measurments.  Choose a Precision Granite USA Surface Plate and you will NOT be dissapointed.
