Abstract
A measuring tape device which includes a casing having an aperture through which a coilable measuring tape can be extracted and retracted. A coilable measuring tape is disposed in the casing with a distal end projecting from the aperture. A first brake mechanism is mounted on the casing for normally applying a controlled drag on the tape which allows the tape to be extracted or retracted against the drag to any given length and held at that length. A second brake mechanism is mounted on the casing and is selectively operable for applying a positive lock on the tape greater in magnitude than the drag of the first brake mechanism, to prevent accidental extraction or retraction of the tape.
