## Questions & Answers

**Q: Do you have to pull or push on unit to release bit?**
A: The collar slides back towards the square end when a bit is locked. So you would move the collar towards the hex end to release the bit.

**Q: will this fit a zyklops speed ratchet?**
A: Yes, as long as you choose the correct Zyklop Speed ratchet "Drive" ie 3/8"

**Q: Is it magnetized? Will it hold my 1 inch screwdriver bits without them falling out as soon as i start to point it in a downward direction?**
A: It is not magnetized as there is not a need. This is a locking bit holder. It locks the bits in to the holder.

**Q: Is this adapter made from impact-rated cr-v or cr-mo steel?**
A: Thought cr-mo was better suited than cr-v for impact use...
