MS17990C — Button R handle (single-acting)

Ring-handle double-acting ball-lock pin (MS17990) — steel. The R-handle offers a secure pull point and easy tethering, while the double-acting design supports both push-button and pull-ring release for quick insert/removal; release to positively lock behind the material.

  • R-handle is easy to grab and accepts a lanyard to prevent misplacement.
  • Positive-locking, tool-free engagement.
