Abstract:
A cornerboard comprising:(a) dual interlocking cornerboard components, the first of the dual components having a longitudinal length and a transverse width and comprising an end section consisting solely of two (outwardly extending) male members extending outwardly from the first dual component at an acute angle in relation to each other, the male members having planar outer surfaces forming a channel opening extending substantially the full longitudinal length of the first component, and the second of the dual components having a longitudinal length and a transverse width and comprising an end section consisting of a substantially trapezoidal shaped channel opening extending subsequently the full longitudinal length of the second component, one of the two male members extending substantially within the full length of the opening, the second component also having a single outwardly extending male member with planar outer surfaces, said single male member having planar outer surfaces extending substantially the full longitudinal length of the second component and being located and extending substantially within the full length of the opening of the first component, the planar outer surfaces of the components being positioned in surface to surface contact to fittingly interlock the first component in perpendicular relation with the second component to form a cornerboard joint.
