The main duct is fastened under the joists; if the branches left from the side and then ran underneath, they would take up even more height. With a top takeoff, the branch goes directly into the space between two joists and runs parallel to them to the \u003cstrong\u003efloor register\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eFive diameters\u003c\/h3\u003e\n\u003cp\u003eAvailable in 4, 5, 6, 8 and 10 in.
