Elesa+Ganter GN 617 indexing plungers are designed such that the plunger set in the end position (spring is "on block") can also absorb axial forces. For applications in which these forces are substantially above the tensile force applied by the operator (Type G), GN 817 indexing plungers are to be preferred.
Steel parts: blackened, plunger hardened
Knob: Plastic (Polyamide PA), black matt finish, not removable.
