Material:
Steel version: Indexing pin hardened: grade 5.8.
Mushroom knob black grey thermoplastic
Version:
Steel version: Indexing pin hardened, ground, black oxidised.
Note:
Indexing plungers are used to prevent any change in locking position due to lateral forces. A new locking position can only be set after the pin has been manually disengaged.
A washer is available to aid by screwing in the indexing plungers. The washer slides beneath the mushroom knob so that the carrier pins engage in the slot.
