ABSTRACT:
A device and a method for measuring linear lengths has a tape housing, a flexible measuring tape, and a rigid rule movably fastened to the housing. The rule can by itself accurately and directly measure relatively small structures and the tape and rule are preferably deployed in opposition to each other to obtain inside measurement results by combining the length of the rule and the deployed length of tape. Angles between the housing and the rule can also be determined or transferred.
