## Questions & Answers

**Q: Does this fit inside 8" duct, or over crimped 8" duct ends?**
A: It fits inside an 8'' duct

**Q: Will this work as the female end for 6" stove pipe?**
A: Yes, it should. You may need to purchase a crimping tool to make it fit. And you will want to add metal screws (just two or three at the circumference) to make it snug.

**Q: Can this metal be cut with metal snips?**
A: No, cutting it would destroy the part for what it is built for

## Customer Reviews

### ⭐⭐⭐⭐⭐ Makes attaching a dryer vent a breeze
*by S***E on April 17, 2025*

Worked perfectly for hooking up a dryer vent. This eliminated having to cut the vent to fit over a non-crimped end coming out of the wall. Don’t forget you will need 1 additional 4” strap, but the ease of installation makes it worth the extra fee cents

### ⭐⭐⭐⭐⭐ What I ordered
*by B***Y on January 10, 2025*

It seems to be a good product. I unfortunately couldn't use it for my project. Fast shipping

### ⭐⭐⭐⭐⭐ Good Product
