This bit of duct work isn't 4" in diameter, as stated in the description. It's 100 mm. Now before you go jumping to "That's the same!", no, it isn't. 4" is 101.6 mm, and that extra 1.6 mm (1/16") makes a big difference when you're trying to get this thing to slide onto genuine 4" duct work. This duct is technically 3-15/16".I had to mangle the already-smaller end of the 4" duct to get it to sleeve inside of this splitter. It's a good thing I'm using sealing tape.You've been warned.

Came i little bent on one of the ends,The side part is welded with dots, and the inside of the joint as a little of over lip material(look at pictures)that will slow air a-bit but i am not too concern.
