Elesa® original design technopolymer plastic crank handles.
EN 570.3 crank handles are connected to a shaft by means of a cross pin and are used for applications where the handpiece has to stay occasionally in its retracted position.
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.
Resistant to solvents, oils, grease and other chemical agents.
Temperature resistant to 90° C (194° F).
Modifications such as inch and metric bores larger than listed, keyways, set screw holes, etc. available upon request.

See our technical section for sizes and tolerances of various modifications.
