A unitary, integrally casted dual C-clamp structure is automatically adjusted by the workpiece during the clamping operation and is formed with clearance areas to facilitate the clamping of an irregularly shaped workpiece. The clamp has a common base. A pair of substantially parallel, spaced-apart supports are formed integrally with the base. Positioned on each support is a respective freely-rotatable, prismatically-shaped clamping block. The clamping blocks are spaced from one another. A slot is formed in the base below and between the clamping blocks.
