January 2012 - GN 927 clamping levers with eccentrical cam in inch and metric sizes are available for rapid clamping and releasing. Unlike clamping operations that use threads, the levers permit torque-free clamping. The levers are designed to ensure movement cannot exceed the maximum clamping position. Additionally, there are no loose components because all are assembled and mounted in their correct order. Thrust forces of up to 8 kN can be obtained with these clamping levers.
