This Half Section Rectangular Stack Duct was perfect fit for my project. I was able to cut a hole to install my outtake fan so i can get rid of the hot air inside my garage. It worked really well, very high quality product for the price paid. I got 2 pieces and they worked well together connecting the two pieces were easy and painless.

Multiple uses
Being in the hvac industry, this product has more than one use. It's typical to install in walls, between floors for supply or venting. I was able to use as complete hood vent in my current operation. I've assembled the rectangular duct, Cut out 3'' x 5' area on the 3 1/4" side of duct, then attached two 8" square to round boots to the 10" side of duct. I can now pull a vacuum across our 5' table.

      Sections do not snap together as expected
      Any video shows that rectangular duct should snap together easily. I purchased 6 lengths to make 3 sections, and none of them snapped together. I used aluminum tape.

        Bought this because I needed a small section of duct. The sides did not clip together properly the whole length of the duct. I got a few spots to snap, but ended up having to tape the thing together to keep it form coming apart.
