Abstract
A mold for making dry cast concrete blocks includes a pair of vertical shoulder forming sections, one along each of the opposite sides of the mold to form vertical front shoulders of a block. Each shoulder forming section has a shoulder roughening arrangement to result in molded, roughened shoulders of the block. Methods of making such blocks and the resulting block are included.
