## Questions & Answers

**Q: What is the ID of the 3inch side?**
A: I bought this for my grizzly shaper with a 3" dust port. the 3" end is the same OD as the shaper. What I had to buy was a 3" x 6" piece of dust collector hose. I think Rockler sells it. Good luck.

**Q: I need a 2.75 Outer diameter to 4”.. will this fitting work?**
A: Read the specs carefully.  It is designed to  connect 4" to 3" dia hose.
