Abstract
A pivoting construction square is provided for measuring angles between adjacent planes, for drafting arcs or circles, and for quickly comparing measured angles to a roof pitch. The device comprises a first and second arm member pivotably attached to one another, wherein the outer ends thereof include apertures for accepting a writing utensil therein. A cross member is connected therebetween, one end thereof being pivotably fixed and the other being slidably disposed within an elongated rail. A locking pin member is adapted to lock the slidable end. Measurement indicia are provided along one arm to correspond to angles, while a quick reference guide comparing angles to roof pitch is also provided. Both arms include a bubble level, while one arm further includes a plurality of aligned apertures to receive a writing utensil. In this way, the device functions as a construction square, a compass, a ruler, and a protractor.
