4 in. x 4 in. x 4 in. Wye is rated 4.6 out of 5 by 11.
Rated 4 out of 5 by from Wye A Four Inch Received the wye via store pickup and it arrived in good shape. Everything fit together as it should with no problems. I would have given it 5 stars if the seams had a tight fit. The seams would have a large leak if not sealed when installed. It is a good product and I would buy again if I need one.

Rated 5 out of 5 by from The Only Way To Solve a Reduced Flow Prblem We were building a very large wood dust collection system which needed to have very free flow - much better than Tees could provide. Unfortunately, I can't provide pictures of just how successful a solution the Wyes provded as the system passes throgh walls and some portions are very high. BUT, early tests of the system indicated 30 - 40% over using Tees and flex duct. Had I known of their of their availability (at store level), i would have designed the system from "scratch" to incorporate this excellent product. The whole prcess from the store to my door was another example of extremely smooth flow.

Rated 4 out of 5 by from Not available in Stores I ordered this 4" duct wye because it was not available in stores. It is all that it is supposed to be. Note: this particular type is not for venting furnace or gas water heaters.
