These are designed to help prevent losing your pins on heavily worn/used items.

Instructions: To Lock:

• Push locking back into pin post firmly.
• Check to see if it’s secured by gently attempting to pull back off of post. If it is secure it will be locked in place.
  
• To release locking back from pin, hold your pin while pulling up on the spring loaded trigger (the top of the locking back).
• Pull up and off the pin.
  
  Do NOT forcefully remove. Avoid accidentally putting your pin through the washing machine with a locking back on as this usually results in a broken pin.
