Abstract:
Concrete molded fence blocks are provided having cores for receiving mortar or aggregate, and pin openings for receiving pins that interlock and align abutting courses of blocks in a fence block system. Groups of a column of blocks form a column support. Standard blocks are provided as spans between the column supports. Column blocks provide additional structural integrity to the fence system, and are larger in comparison to the standard blocks. The leading and trailing edges of the standard blocks have complimentary shapes to provide further interlocking capability between individual blocks. Various types of column blocks are provided for managing the layout of a particular fence system.
