| Our color system assures selection of the right thickness every time. The color coding means fewer operator mistakes. And inventory control is simplified because what's in stock is highly visible. Our shim stock is manufactured from high quality plastic. It is impervious to oil, has minimum compressibility characteristics and is easy to cut. |
