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
  • Interior fittings
  • DIY
  • Furniture and joinery works
  • Secure quickly with self-adjusting clamping width
  • Clamping tools are not suitable for lifting, pulling or transporting.
  • Clamping tools may only be clamped manually without using any auxiliary tools.
  • Improper use can cause personal injuries or material damage.
  • Never change or modify clamping tools. Only use them in their original condition. Only use original‐spare parts if required.
  • Sheet metal parts made of tempered steel, nickel-plated
  • Spindle made of steel, galvanised
  • Handle made of 2-component plastic
  • Protective caps made of plastic
  • Clean the rails with solvent
  • Clean and oil the spindle regularly
