## Questions & Answers

**Q: Is this correct suze for receptacle plate covers on a outlet?**
A: It’s too narrow.  A 3/16” tip makes it a little easier not to scratch a new stainless plate cover, but a 1/4” tip will also work as long as the tip isn’t off center of the screw.

**Q: Will it fit in your brest pocket?**
A: It will fit. But its probably a little bigger than you would want to carry in your shirt pocket.

**Q: Is the head small enough to adjust sprinkler heads?**
A: Yes I have used it in my Rain Bird nozzle heads. Usually I use it for Phoenix connectors in home theater and home automation though.
