            Shoddy Quality Control
            I have a 10" x 3.25" duct to connect to. Bought this off the shelf. Brought to jobsite with other materials and it doesn't fit over the duct it's supposed to. Please see pictures. Quality control is lacking here. Home Depot, I'm calling you out on this.

              Worked well with my range hood duct, but it is a bit fragile. One of the spot welds broke while I was drilling the holes to attach it to the duct. I doubt it would hold up to using self tapping screws.
