ABSTRACT:
A level angle gauge is used to capture an angular measurement on a structure. The level angle gauge includes an elongated body structure, a leveling element connected to the body structure, an arm structure pivotally connected to the body and an arm lock mechanism that locks and unlocks to allow and inhibit pivotal movement of the arm structure. The body structure has opposite sides and a reference surface extending therebetween. The arm has an arm surface that is in a common plane with the reference surface in a first position. The arm lock mechanism being dimensioned to be less than the width of the reference surface. The body structure is formed as a web having opposite flange, one of which is foreshortened. The arm structure includes a pair of parallel arm members such that the web of the body structure interposed therebetween. A connector piece joins the arm members, and a notch is provided in the web to receive the connector piece when the arm structure is in the first position.
