Toggle Clamps By Perfect Corporation

Our range of Toggle Clamps are used for temporary clamping that can be employed and released easily via the motion of a handle, lever, or pneumatic switch. Different applications for toggle clamps require different configurations, including vertical, push-pull, cam, latch, and hook designs. They also require different sizes and clamping pressure.

Toggle Principle
Toggle action clamps operate through a linkage system of levers and pivots. The fixed length levers, connected by pivot pins supply the action and clamping force. Toggle action has an over centre lock point which is a fixed stop and linkage. Once in the over centre position, the clamp cannot move or unlock unless the linkage is moved. All types of toggle clamps have same action, just oriented differently.

The Toggle Mechanism in a clamp has three functions.
To multiply applied load at the handle into a high clamping force to hold the work piece.
To create an over - centre lock to prevent the clamp from opening & releasing the work piece until opened by the operator.
To rapidly open & close the clamp giving a maximum clearance in which to load & unload the work piece.
