The PuckChuck is a low profile, modular zero point clamp & quick-change pallet system by Saunders Machine Works. Automatic receivers repeatably clamp pullstuds with three spring-driven clamping jaws, which are released when air pressure is applied to the receiver (loss of air pressure ≠ loss of clamping force!)

This system is designed with modularity in mind: the PuckChuck system doesn't lock you in to a set number of clamps or a fixed pallet size like other similar systems on the market. Place as many (or as few) PuckChucks as you like on your table to accommodate fixtures of any size.
