Quick-Clamp 

Quick-Clamp – secure, fast, easy.
This proprietary workholding technology from Datron features pneumatic , shortstroke clamps that minimizes setup time for redundant processes. The user-friendly, one-button operation allows the user to open and close the clamp with one hand while the free hand sets the workpiece. Plus, your investment is protected by "sacrificial jaws" that can be removed and replaced when they get worn or marred over time.
