ABSTRACT:
An adjustable measuring gauge has at least two sized and shaped operatively associated members made of a durable material. The lower member has an upper side and a first elongated and square side edge with a plurality of measurements beginning at zero marked at the upper surface. At least one upper member is slidably and adjustably connected to the lower member and has a second elongated square side edge disposed in assembled position on adjustable movement of the upper and lower member to uncover and reveal the desired measurement marked on the lower member. Elongated aligned slots and threaded pegs are provided to achieve unidirectional movement for an accurate measurement. A clamping assembly is provided to both hold the operative associated members so the adjustable measuring gauge can be reused for another measurement; further, a non-skid fabric on at least the upper member to facilitate use and handling.
