## Questions & Answers

**Q: is this good for outside angles as well as internal? how accurate is it for use with a mitre saw?**
A: Yep, does both internal and external angles (just fold it back on itself for externals). Accuracy is absolutely spot on. 
For cuts on a mitre saw it will give you both a single cut angle (eg. single shelf into a corner) and a mitre angle too (eg. skirting in and out of a corner). 
As a carpenter I wouldn't be without it!
