G70x arm clearance with Kickback-Link on older Walter Klassen vest: socket block options and workarounds.
DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- When the Kickback-Link is correctly oriented, it contacts a ratchet on the Walter Klassen vest even with an Apex-extended arm stopper and fully extended carbon arm; reversing the link reduces range of motion slightly.
- The standard solution is a solid socket block without spring or Kickback mechanism from Klassen (WK), which operators report as safer and providing proper clearance from the G70x; it is no longer listed by WK but is worth requesting.
- A front-mount block used on a back-mount configuration is disadvantageous for several reasons.
- A workaround involves placing a large washer under the return spring stop to push the linkage away from the vest, but this increases spring tension and accelerates wear.
- One operator considers the G70x to have the poorest offset for back-mount use, preferring the G50x for its straighter geometry; another operator sold a G70x for this reason.
Depends on
- Solution effectiveness depends on vest age and configuration, arm length, and individual geometry preferences.
- Compatibility between Kickback-Link orientation and ratchet placement varies.
- Solid socket block availability from manufacturer.
