ABSTRACT:
A measuring gauge for measuring both inside and outside diameters. The inventive device includes a main body having a plurality of extension members telescopingly received therein which may be extended therefrom to various lengths. The device further includes a pair of pivotally mounted OD legs operable to engage the outside surfaces of an object being measured, and a pair of pivotally mounted ID legs operable to engage the interior surfaces of the measured object. The OD legs and the ID legs are aligned such that indicia provided along the device can be used for both inside and outside measuring operations.
