The Comparator Square is normally used with the Taft-Peirce Cylindrical Square to obtain direct readings of work squareness. It may also be used effectively with other vertical master reference surfaces. The popularity of this precision inspection tool lies in its positive operation that eliminates the guesswork hazards of sighting and using feelers. The Comparator Square requires no operator skill other than the ability to read an indicator.
