The ratchet clamping works on the principle of a toothed system with a lever that allows for gradual tightening of the jaws. It is very fast and efficient, yet provides a sufficiently strong clamping force. Ratcheting clamps are often operated with one hand, which makes it easier to work when assembling structures or during assembly. They are suitable for medium-duty joinery work and are popular for their simplicity, speed of use and quick-release capability.
