ABSTRACT:
A miter is aligned and locked during assembly without the use of tools by engaging a dowel perpendicular to the faces of the mitered parts with a corresponding bore while the mitered parts are non-coplanar, and then twisting the parts about the dowel axis into a coplanar position in which they are interlocked by a key on one part cooperating with a recess on the other.
