ABSTRACT:
A square for glass cutting has a triangular shaped phenolic plastic body having a head supporting base member, a straight edge, and a straight edge strengthening member. The base member has a plurality of apertures having diameters of a first dimension. A head member includes first and second head plates interconnected and spaced by a bridge to sandwich the base member. The first and second plates have a plurality of apertures having centers corresponding to the centers of the base member apertures, but having diameters of a second dimension less than the first dimension but equal to the diameters of set screws, whereby when the head member is loosely attached to the head support member by the set screws the squaring of the first head plate automatically squares the second head plate and the tightening of the set screws maintains the squared relationship between the head plates and the straight edge member. The support member forms the hypotenuse of the right angle triangle and provides straight edge strength at the top where needed and base member support to prevent rotation of the straight edge member.
