    Rated 5 out of 5 by from duct transition The product arrived in a timely manner which was great as I had ordered the wrong size the first time. My husband easily installed this duct transition onto our new Broan range hood and connected to the 7" exhaust pipe that was original. Everything fit perfectly and it works great.

    Is the round offset

    The photo on the website shows the round to be off center. Is the round off center? If not is there one that is off center like the photo shows?

    Thank you for your question on the model 412H duct transition. The picture shown is not the model 412H. The 412H is not offset. We do not have a 3-1/4” x 10” to 7” round transition that is offset.

    Thank you for your question on the 678 exhaust fan/light. The 678 requires four inch duct work. We would not have a conversion kit for four inch to seven inch duct.

    Which side is the front side of the Transition Model 412H?

    Someone has installed this over my range and it appears that it has been installed backwards.

    When do you need a 412H NA (taller one) compared to 412H.

    Cabinet bottom is 3/4" thick.
