An improved level assembly includes a generally rectangular level, an elongated generally rectangular blade, one end of which is pivotably secured to the level to permit movement thereof about an axis normal to the longitudinal axis of the level, a scale element having scale markings formed thereon for indicating angle degrees and a pointer element disposed for cooperative association with the scale element for indicating a specific degree of angle. Either the scale element or the pointer element is fixed to the level and the other element is coupled to the blade for pivotal movement therewith. The level assembly permits the user to accurately align workpieces at a predetermined angular orientation.
