It transitions from round duct to a floor or wall register opening, redirecting airflow at a 90-degree angle through a rectangular outlet. The boot features a 6-inch inside diameter round inlet and a 3-1\/4-inch by 12-inch rectangular outlet face, making it a standard size for supply-air floor boot applications. Fabricated from galvanized steel at standard gauge, it resists corrosion in typical HVAC environments. HVAC installers and sheet metal contractors handle this fitting during new construction and system modification work.\u003c\/p\u003e\n\u003cp\u003eThis stack boot is suited for forced-air supply duct systems where a vertical duct stack feeds a floor or baseboard register. The 6-inch ID inlet connects directly to 6-inch round duct or collar takeoffs from a trunk line. The 3-1\/4-inch by 12-inch rectangular outlet aligns with standard floor register openings of the same face size. It is commonly installed in residential construction, light commercial tenant improvements, and duct retrofit projects where floor-mounted registers are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree turn geometry routes airflow from vertical duct stack to horizontal floor register plane\u003c\/li\u003e\n  \u003cli\u003e6-inch inside diameter round inlet fits standard 6-inch round duct and snap-lock collars\u003c\/li\u003e\n  \u003cli\u003e3-1\/4-inch by 12-inch rectangular outlet matches standard floor register and boot dimensions\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction provides corrosion resistance for long-term duct system use\u003c\/li\u003e\n  \u003cli\u003eStandard gauge fabrication meets typical residential and light commercial duct installation requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting compatible with standard 6-inch round residential and light commercial forced-air supply duct systems using 3-1\/4-inch by 12-inch floor registers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal contractor. The air handling system should be powered down and the blower confirmed off before cutting into any existing ductwork. Sheet metal screws and UL 181-listed duct tape or mastic sealant are used to secure and seal the boot to the round duct inlet and the subfloor register opening. Local mechanical codes based on the IMC or SMACNA standards govern duct installation practices and should be consulted before work begins.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Fitting Type\u003c\/strong\u003e: 90-Degree Stack Boot\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Round Inlet)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRectangular Outlet\u003c\/strong\u003e: 3-1\/4 inches wide x 12 inches long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 8.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141700\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 57531261\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721155412274,"sku":"57531261","price":52.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f833de5f01d2c3049e6e57f91c386d2_feee22ff-b5c7-4596-8fc2-6498c05c2fe1.jpg?v=1788574513","url":"https:\/\/voomisupply.com\/products\/value-collection-57531261-galvanized-duct-90-stack-boot-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
