 Handwheels GN 322.3 with retractable handle are for applications, where the handpiece must not protrude.

These handwheels have the distinguishing feature that the handle and the retracting mechanism are completely encased within the rim of the wheel.

The handle is pulled out of its taper seating in the direction of the arrow and then tilted. A compression spring locks the handle in both end positions.

A positive lock is achieved in the operating position by way of a taper seating.
