ABSTRACT:
An end wall comprises a plate having a smooth, plane fromt surface whereas its rear side is stiffened by radial ribs and annular ribs. A central insertion pin is provided on the front side of the plate. Each of the four side walls of the plate is equipped with stacking bosses limiting stacking pockets which are of complementary design to the stacking bosses. When vertically aligned end walls are being stacked side-by-side or one above the other, the stacking bosses and the stacking pockets of one side wall can be joined to the complementary stacking bosses and stacking pockets of a side wall of another end wall without a joint. Corner surfaces of the end wall are rounded off and provided with cylindrical locking bosses which have the same radius as the rounded corner surfaces.
