ABSTRACT:
The corner post of the present invention is constructed from a one piece blank of cut and scored corrugated paperboard that includes an integral locking means for securing the corner post in its usable condition. The corner post blanks are normally shipped and stored in a flat condition, and are folded into a generally quadrilateral cross sectional shape for use. When so folded, one or more pairs of locking tabs and ears, that are formed integrally with the blank, are engaged to lock the corner post in its quadrilateral shape.
