💡 Where should I place a spring plunger locking pin when setting up a custom fixture board to keep things handy?
You want the unit seated flush against your backing plate so the ball nose grips the target spot securely.
- Thread the housing straight into pre taped holes until it sits level with your material
- Align the pin drop zone away from sharp edges so the rolling tip catches clean flat areas
- Spread the locking points apart to cover the full footprint and stop sliding during heavy duty runs
