Ready to go – the first time and for quick set-up during workpiece changes

BESSEY STC toggle clamps adapt to workpieces of varying thickness – without manual setting of the spindle and, with practically the same clamping force:

  • due to an automatic clamping width range
Uncompromisingly versatile

One size of the BESSEY toggle clamp replaces multiple competitor sizes simultaneously:

  • due to an extremely large clamping range, thanks to the patented mechanism
Powerful and gentle

Even sensitive workpieces, e.g. with veneered or varnished surfaces, can be gently clamped:

  • due to moving pressure plate with removable protective cap
  • due to clamping force regulation via adjustment screw in the joint
