ABSTRACT:
A collapsible, self-locking load block of the type used as dunnage to prevent cargo from shifting in a truck or rail car body. The load block is formed from a one-piece blank of foldable sheet material, such as paperboard, and includes opposed pairs of side walls joined to form an open-ended, tubular structure that is generally rectangular in cross-section with its width, length, and height of different dimensions. The load block also includes internal center panels extending diagonally between opposite corners of the tubular structure.
