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.

I needed to connect the 4" outlet on the back of a clothes dryer to a 3" vent pipe coming out of a wall.I had purchased a pvc adapter at the hardware store, which worked but was so large that it pushed the dryer too far away from the wall. This adapter is much more compact, works well.

I use this fitting for part of my dust collector with aluminum tape. It works great. it doesn’t fit on the dust collector but with the tape it’s a pretty solid connection.

Excellent 10” to 8” duct reducer. It’s very round and fit great where I needed it

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!

Mi serviva una specie di imbuto per l'inserto che scorre nel caminetto. Funziona perfettamente.
