BESSEY all-steel screw clamp GZ-K, toggle handle & low overall height up to 6,000 N

BESSEY All-Steel Screw Clamp GZ-K – Toggle Handle with Low Profile

The BESSEY All-Steel Screw Clamp GZ-K offers the proven GZ clamping force of up to 6,000 N – combined with a classic toggle handle with rounded ends. The decisive advantage: The low profile of the toggle handle allows for use where wooden or 2C handles no longer fit – ideal for clamping tasks with limited overhead space. Made in Germany.

GZ-K or GZ – when is the toggle handle worthwhile?

Whenever overhead space is limited – e.g., under tables, in drawers, on machines, or during assembly work in confined spaces. The toggle handle sits lower than a wooden or 2C handle, allowing clamping even where other clamps cannot be used. The clamping force remains identical: up to 6,000 N.
