What is the diameter of the circle inlet? Mine is about 3 and 3/4 inches and I need it to fit exactly over my duct. Please help.

The outside diameter of the plastic flange that surrounds the screen and fits in the vent hole is 3 3/4". The inside dia is just slightly less, about 1/8 of an inch less. Hope this helps! Mine fit perfectly.

I would guesstimate the diameter to be a little more than three inches, maybe 3 1/4 inches. If you need an exact measurement, let me know.

You're in luck because I just used the old tub nipple and had the new one still in the drawer to measure, it is 3/4". I just left my old one in place and turned the new spout onto it. The spout is plastic. You could call delta to double check.

I installed this last night and I can say for sure the pipe is over 3 inches. I measured the full length and got roughly 3 3/8ths of an inch. Hope that helps!

yes 21/2" on inlet and outlet. it made my gsr swapped civic sound a little quieter with less drone/rasp. When I redue my exhaust to a 3" I might use 2 of them. the only downside is they're heavy

The ouptut duct for this model is 4" in diameter. If you are replacing an existing exhaust fan, you will probably have a 3" plastic flex duct vented directly into your attic which is not code compliant. Correct way is to replace the 3" plastic duct with a 4" insulated duct and vent to the outside directly. If you use the existing 3" duct, you will have to purchase a 4" to 3" adaptor. Hope this helps. AMGContracting

This is a very important issue. Yes, it's a 3/4" pipe thread at the inlet, but inside, the outlet opening is restricted down to about 9/32". So, you lose about 2/3 of your flow. I was redoing my long drip irrigation lines where I needed to maximize the flow. I returned mine and bought a bunch (14) at a big box store (blue/gray colors), which had much less restriction. In my opinion, it's more a volume issue and not so much a pressure issue, as the higher restriction increases the pressure, but lowers the volume. Now I get the flow I need. These are, however, nice little, well-made valves and I'd use them on an application where I didn't need that much volume. This is a very important issue.

Jimmy, I am using 4" duct (actually sewer pipe) through out my shop) and it is proving very effective) with gates to limit the collector to one machine at a time. I can't say that it won't work, but it will not be as effective since the airflow is limited by the 4" connection. Not worth the $.

I'm sorry I do not I sent it back but do you know your exhaust pipe size? I will tell you if it will fit or not if you could measure it for me I can tell Ya if I will or not!!

Hi Gregory. Don't know if you've already received a response, but the hole needs to be 3/4".

I think you mean the diameter of the tubing? It's about 3/4". The tubing is smooth and rounded, should slide into a tight spot easily.

Do I have a "BUF23"? Don't really know but whatever is hanging out there is more like three inches in diameter, I'd say. Don't know of this helps. Good luck!

the problem with this grate is that there is a flange on the back which may impede your ability to fit this over a duct. My best advice is to write the manufacturer or buy this from someplace you can return it easily

6". I fitted mine with 4" ducting. I have 2 tents but the "exhaust sleeve" faces a different direction from each other. Also, the exhaust holes are a couple inches differently placed from one tent to the other.

I measured it , it is 3/4 inch o d . You will need a reducer . Which is very cheap. I hope this helped.

I know we used 4" duct on all the exhaust fans. Some of them were oval and some were round, so I'm not entirely sure about this one. However, it was close enough that we could use flex duct without an adapter.
