Abstract: A clamp suitable for masonry work can securely and simultaneously accommodate a plurality of bricks, blocks, stones or other masonry materials during cutting operations. The clamp may be readily set up at a construction site and provides for rapid and consistent measuring, marking and clamping of bricks allowing more precise cuts of multiple bricks in a single cutting action. The clamp comprises a first fence defining a first workpiece bearing surface, a second fence defining a second workpiece bearing surface positioned in a laterally spaced relation to the first fence, and optionally, a third fence defining a third workpiece bearing surface positioned in spaced relation from the first and second fences. A clamp operating device is provided to selectively clamp and release a workpiece between the first and second fences.
