## Questions & Answers

**Q: Why do these look remarkably different both in form and in length ?**
A: I do not really know what you are referencing.... what you received, I presume, does not match what is pictured?

**Q: What’s the total length of the 6” TO 4” reducer?**
A: don't know.  I have the 8"to 6" reducer.  7 1/2"

**Q: What are the internal diameters of the 10" to 6" reducer?**
A: The product is 10 x 6 reducer. The connecting vent will connect on outside of unit. Oneside 10 inch other 6 inch.

**Q: Can it be used to increase from 6" to 8"?**
A: Yes. But it won't work as in either direction. If you want to go from 6 to 8" you would have to crimp (or have a sheet metal worker crimp) the big end. If you want to go down from 8 to 6", then crimp the small end. If this isn't clear to you, then go to a shop that sells lengths of sheet metal ducting and take note how one end of each piece is krimped. Take note that the gas flowing  through the tube or duct flows toward the crimped end.
