  • Extremely easy to open, the release lever is under your thumb when you want to open the fitting, ergonomic.
  • Resistant to accidental disconnection when being dragged. The release lever opens in the direction opposite to the cam arm, so movements that tend to open the release lever also tend to close the cam arm.

  • Note: If the rotating lever is not flush with the handle, it is not properly engaged.
