Abstract: A micrometer holder is disclosed. A micrometer is a precise measuring instrument that should be protected against damage by impact and rough handling. The device disclosed herein has a pocket large enough to receive the measuring section of the micrometer and shoulders at the side of the protector extend out in front of the micrometer body. The outer sheet forming the micrometer holder is substantially longer than the inner sheet so that the holder is held in a shape to conform to the body of the wearer when the micrometer is worn on a belt so that the micrometer is held against inadvertent removal from the holder when the person leans over or the holder is jostled. The upper edge of the front of the holder is shaped to hold the rounded edge of the micrometer.
