Product description

For cam action indexing plungers GN 721.1 the plunger pin is withdrawn by turning the lever arm by 180°. The limit stop provides a safety feature whereby the lever arm can not be turned by more than 180°. The notch allows for safe positioning while the plunger pin is held in the retracted position.

When the cam action indexing plungers are positioned symmetrically, the left or right-handed types allow for a practical, i.e. equal, direction setting of the lever arm.

The plastic ribbed sleeve offers an aesthetically pleasing and comfortable finger grip.
