Installation Notes

Gage blocks are precision metrology tools and should be handled by qualified calibration or quality control personnel. Store blocks in the provided case and keep surfaces clean and lightly oiled when not in use to prevent corrosion. Wring blocks together on a clean, flat surface using controlled lateral pressure. Do not drop, stack improperly, or expose blocks to abrasive surfaces, as damage will affect measurement accuracy.
