Lock-out Pull Pins with Clamping Knob

Locking pull pins with Clamping Knob|One-Handed Operation × Pause & Lock × Precision Adjustment

The Lock-out Pull Pins with Clamping Knob feature a temporary hold mechanism that keeps the pin in the retracted position, freeing both hands for precise adjustment. After adjustment, a simple turn of the knob re-engages the pin into place.


Lock-out Pull Pins can be pulled up and then rotated 30 degrees to maintain the pull-up position. It is convenient for the user to adjust the assembly with both hands, and after adjusting to the desired position, *turn the knob directly to insert it back in.

*The old version requires "pulling up again and rotating" to insert the pin, while the new version requires direct rotation.

Locking pull pins also supports manual tightening to clamp components firmly without tools. ROHS certified and globally applicable, it’s ideal for modular assembly lines and complex equipment setups.

Key Features
  • Lock-out hold by turning the knob—no need to pull again
  • One-hand operation for enhanced efficiency
  • Manual clamping function adds stability
  • Designed for safety and ease of use
