## Questions & Answers

**Q: Will this work for an air intake or is it only made for an exhaust line?**
A: It's made to work as an exhaust and the flap to close by gravity when not in use. I guess you could take the flap off since its just a little plastic flap piece and make it into an intake with some kind of filter Jerry-rig or what ever your intended intake would need.

**Q: What size hole saw is needed for installation? Since Amazon has it as an add on item I figured I'd buy a hole saw set too.**
A: 4 1/4"......if you plan on connecting something to it the added 1/4" gives you a bit more room.  i found it better than a 4" hole.....

**Q: Do you make the Lambro under eave vent in brown?**
A: I only saw white

**Q: What is the diameter of the cylinder?**
A: 4in
