Abstract: An apparatus including a rectangular, vertical framework, including a series of spaced vertical bars to define a grid, with a lower slotted support bar and an upper bar enclosing the framework, wherein the bottom slotted bar includes a plurality of orthogonally and slidably mounted support legs adjustably positionable to accommodate various sized masonry block to direct the legs through the apertures within the block. Pneumatic tires of an enlarged diameter, such as two 4.80.times.400-8 inch two ply air tires are mounted rearwardly and below an intersection defined by the legs and the rectangular framework and to each side of the rectangular framework to afford stability to the organization. An accessory locking frame is mounted within the outwardly extending legs and affords a degree of flexure to enable securement of stacked masonry block to the dolly.
