The DeFelsko STDCS40, Certified Plastic Shim, Individual Certified Shim, 40 mil, White is a set of shims that simulate a coating over a particular substrate material or shape. The shims allow users to check coating thickness gauge performance and help with calibration adjustment.

They can also be placed on top of soft or tacky coatings to obtain thickness measurements without the probe having to make direct contact with coating material.
