Primary Applications​

This versatile toggle clamp is ideal for quickly securing workpieces across numerous sectors:

How It Works (Operating Principle)​

This clamp operates on a powerful over-center toggle mechanism. The blue handle acts as a lever. Pushing it down engages the clamping arm, which moves through an over-center point to lock securely, applying the full 2743N force to the workpiece. The adjustable screw allows for precise setting of the clamping arm’s reach. Pulling the handle up quickly releases the tension and retracts the arm, enabling fast loading and unloading of materials.
