Features and applications
Adjustable handles GN 300.4 allow a higher tightening clamp force. The clamping element is not in direct contact with the plane to be clamped. Clamping is made by the distance bushing with large base, which does not rotate on the plane. The bushing contains a set of balls which reduce to a minimum friction between the part which rotates with the lever during clamping and the distance bushing.

Instructions of use
For clamping, lift the lever to disengage the clamping device teeth and bring it back to start position. By releasing the lever, the return spring automatically engages the teeth.
If the lever cannot make a 360° rotation, the clamping element can be easily screwed by means of the hexagon socket front head screw (after having disengaged the lever).
