If you're into locksmithing as a hobby or even as a pro, you know the pain of springs and pins flying everywhere when you take a lock apart.

That's where these plug followers come in.

This set gives you four of the most common sizes you'll need (0.5\, 0.55\, 0.498\, and 0.398\) all made from anodized aluminum, so they're light but durable and have a nice bright black finish.
How do they work?

When you're removing the core (the plug) from a pin-cylinder lock, you slide one of these followers in behind it.

It holds all the driver pins and springs in place in the housing, so nothing goes shooting across the room.
It makes re-keying, repairing, or just taking a lock apart for fun way less frustrating and way more professional.

A must-have little tool for your lock-picking or repair kit.
