Primary Applications:​

This safety locking clamp is specifically designed for applications requiring both quick operation and secure holding:

How It Works (Operating Principle):​

This clamp operates on an over-center toggle mechanism with a safety locking feature. The blue handle serves as the operational lever – pushing it down engages the clamping arm and activates the over-center locking action. The unique safety lock​ mechanism prevents the handle from being accidentally lifted once engaged, ensuring the workpiece remains securely held. To release, the lock must be deliberately disengaged before lifting the handle, providing an additional layer of operational safety.
