A corner support post formed from a paperboard tube includes a substantially planar outer wall and an inner wall coextensive therewith and provided with a shoulder defined by a laterally turned portion of the inner wall. A compression accommodating bead is formed from the outer wall and extends into engagement with the inner wall between the shoulder and a first end wall extending between the outer and inner walls. A second end wall, opposed from the first end wall, extends between the outer and inner walls with the outer wall, from the shoulder, inclining toward the outer wall and terminating at the second end wall.
