  • Patent number: 6928933
    Abstract: A printing press racking board and corner angle support, both preferably formed via injection molding processes. The racking board is a generally flat member having stiffening ribs and stiffening rod inserts attached to the bottom surface so that the board can exhibit the required stiffness. Hand holds and finger holes are included to facilitate moving the racking board. The corner angle support has two members extending perpendicularly from each other. Each member has flanges which can support a racking board, and each member also includes stiffening ribs to increase stiffness. The racking board and supports are both lighter than the prior art, and yet both exhibit the required stiffness. Also, racking board and supports are less likely to splinter and fracture, and thus exhibit a longer user life.
