Size matters
Great if you want to lose some inches. Size matters here

It works!
I use this fitting for part of my dust collector with aluminum tape. It works great. it doesnโt fit on the dust collector but with the tape itโs a pretty solid connection.

quality reducer for exhaust use
This thing is decently constructed, easy to work with and priced fairly. I used it to neck up from 3" to 4" ducting, reducing pressure in my bathroom exhaust system. Which allowed the pipe clamps to retain the ducting better. Would buy again.

Heavy
Was looking for a 12 in reducer for hvac. And this was about all I have been able to find to date. It is nice but heavy for the use I needed so will possibly have to add some extra support for it.

Couldn't be any better.
So often dust collector fittings are too loose, or too tight, or too thin, or too whatever. In this case, the 6 to 5 adapter was perfect-- allowing me to connect my 6" DustDeputy port to a 5" hose without leaks. Furthermore, it is a seamless made from heavy guage metal so no bending or distorting. Well worth the extra couple of extra dollars compared to standard sheet metal fittings.

Great solution for inset drier vent issue
A perfect solution for us. Old house didnโt have space around existing drier vent pipe.

Accomplish as much "prep" work as you can before going into the 100++ degree attic
My old fan exhaust vent outlet was a 3-inch and my new fan is 4 inch. I couldn't replace the ducting itself as it went into a very tight area, so the only thing to do was adapt from 4 inch to 3 inch. After I put everything together, I went into the attic, pulled out the old and put in the new. Using aluminum tape, I was able to tape the adapter 3 inch outlet to the ducting, and get out of the 100+ degree attic. I then went to the laundry room and had a perfect guide to make a larger hole and install the cover

Worked great/As expected and still kicking!
There is not a lot to say. We got this for a portable air conditioner. We literally put a hole in the wall and connected the exhaust to this. Again worked great shipped good! TY!
