It transitions from a rectangular duct collar to a round branch run, allowing installers to tap off the top of a main trunk duct. The adjustable design accommodates variations in duct height during rough-in, making field fitting faster and more forgiving. With a face size of 6 by 7.5 inches and a 1.25-inch rise, this fitting is sized for residential and light commercial forced-air distribution systems. Sheet metal mechanics and HVAC installers handle this type of fitting during duct fabrication and installation.\u003c\/p\u003e\n\u003cp\u003eThis takeoff is intended for top-entry branch connections off a rectangular trunk duct in forced-air heating and cooling systems. The square-to-round geometry directs airflow from the main duct into a round branch duct or collar. The adjustable feature allows the fitting to be set at the correct height to match the duct or insulation wrap thickness on-site. Typical applications include residential new construction and retrofit duct systems where branch runouts connect to diffusers, registers, or flexible duct.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSquare-to-round transition allows a rectangular duct collar to feed a round branch runout\u003c\/li\u003e\n  \u003cli\u003eAdjustable rise design accommodates field variations in trunk duct height\u003c\/li\u003e\n  \u003cli\u003e1.25-inch rise suits standard residential trunk duct installations\u003c\/li\u003e\n  \u003cli\u003e6 by 7.5 inch face dimensions fit common residential and light commercial trunk sizes\u003c\/li\u003e\n  \u003cli\u003eTop-entry orientation keeps branch connections clear of floor or ceiling obstructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for use with standard rectangular trunk ducts in residential and light commercial forced-air HVAC distribution systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by sheet metal mechanics or licensed HVAC technicians during duct system fabrication. Power down the air handler or furnace before cutting into an existing trunk duct.
