ABSTRACT:
A fixture for holding workpieces at predetermined angles while they are being interconnected includes a pair of legs and a hypotenuse forming a right triangle, whose three vertices are truncated to enable the fixture to function as a jig, as a template, or as a bending tool. Workpieces may easily be attached to the fixture, obviating the need for special clamps.
