Wood Floor Block

A block with the opposite faces generally parallel used in the construction of block floors. It may be a single-piece block, or a fabricated block made of two or more pieces of wood securely joined together. In either form, the vertical faces, or sides, of the block are usually milled for joining to other blocks, generally with tongue and groove or with grooves for splines. It is so milled that the grain of the wood runs horizontally or in a direction perpendicular to the top surface of the block.
