4" Inch T-Shape Ducting Splitter - 90 Degree Galvanized Steel 3-Way Dust Collection Fitting - Branches for Exhaust Fan - Ducting Adapter - Duct Hose Connector

Great product. This is the second one I have ordered.

Perfect! Arrived in great shape.

Product was exactly what was needed. Received in great condition, machine placed into service.

Product is heavy gauge with 100% of the seams being sealed on the inside. Quality is much better than off the shelf DIY brand stores - item at DIY was not available unless special order. Great find and was in my hands in 24 hours.

This thing is really well-made, I was impressed. It fits like a glove, honestly. The price is a bit steep though, gotta say. Might be worth saving up for if you really want it. Overall, pretty happy with the purchase despite the cost.

Awesome perfect fit heavy duty, well worth $$

This wye does not fit well with standard North American Duct Work. After crimping and hammering I cannot insert my fitting all the way per the picture.

Worked perfect. Was used to join two 4" bathroom exhaust ducts into one 6" wall cap.
