The shape of the crank handle with retractable hand piece GN 472.3 is modern, attractive, and meets all demands of industrial designers.
It is a further improvement on the standard crank handles with retractable handle and is mainly used where the application requires the crank to be used in a more confined area of the equipment. The hand piece folds into the recess of the arm.
In the operating position the hand piece is firmly locked.
By pulling the hand piece in axial direction out of its locating cone, it can be folded back into place.
The spring holds the hand piece firmly in both positions.
When folding the handle back it will automatically snap back into the recess. 
Special inch and metric bores, squares, keyways, set screw holes, etc. available upon request.
See our technical section for sizes and
tolerances of various modifications.
