ABSTRACT:
An attachment for a carpenter's folding ruler has an elongated body with a longitudinal slot. The slot is dimensioned to accept the ruler and the ends of the body have flat sections against which part of the ruler can be folded to form certain angles. One of the ends makes a 90.degree. angle with the axis of the slot while the other end is at some angle less than 90.degree.. A level is provided on the body so that it may be vertically or horizontally positioned.
