## Questions & Answers

**Q: Can i use powertecs 70190 y-fitting, 4 x 2-1/2" fitting with this? will the y fitting plug into this? i need to mount it to a router cabinet.**
A: I couldnt say for sure. I know that the WEN brand clear 4 inch hose is VERY tight around this. I did not need a clamp to hold it in my application.  At $6, if it didn't is is still a handy part to have around for future use IMO.

**Q: Is the inside diameter at the flange end larger than 4 inches; it appears to get wider on the outside of the fitting, does it expand on the inside too**
A: I already have it mounted and can't tell for sure, but I think the interior is the same size all the way down..  I have inserted a 4-inch hose and it appears to be flush at both the top and bottom.

**Q: I know its not meant for this use but could it be sturdy enough to put in a subwoofer box as an aero port.**
A: This component is "hard plastic" but definitely appears to have a lot of strength (and the specs, that I don't have in front of me, identify a certain "weight" loading that they can withstand). I am using them for supporting wood railing in my corral for my horses, and they are holding up 50-100 pound log rails. I don't know how much your subwoofer weighs or what an "aero port" is, but if the subwoofer weighs less than 50 pounds, this will work just fine.

**Q: will 4" drain pip[e connect to this snugly enough to use on a rain water catchment system. The flange mounting on the lid of the tank?**
A: Do not know what inside diameter is of 4" drain pipe.  This is designed for 4" dust collection hoses.
