It transitions from a round duct trunk to a rectangular floor or wall register opening, making it a standard component in forced-air supply distribution. The boot features a 6-inch inside diameter inlet and an overall rectangular outlet measuring 2.25 inches wide by 10 inches long. Overall height is 7 inches. Constructed from galvanized steel at standard gauge, it resists corrosion in typical installed conditions. HVAC installers and sheet metal contractors use this fitting when roughing in supply air runs that terminate at floor or baseboard register locations.\u003c\/p\u003e\u003cp\u003eThis stack boot is suited for new construction and retrofit ducting applications in residential forced-air heating and cooling systems. It is commonly installed where a 6-inch round supply duct drops into a floor joist bay and connects to a 2.25-inch by 10-inch floor register boot opening. Its 90-degree configuration directs airflow from a vertical or horizontal trunk line into the register cavity without requiring additional offset fittings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-inch inside diameter round inlet for direct connection to 6-inch round duct\u003c\/li\u003e\n\u003cli\u003eRectangular outlet sized at 2.25 inches wide by 10 inches long to match standard floor register openings\u003c\/li\u003e\n\u003cli\u003e90-degree configuration routes airflow efficiently into floor or wall cavities\u003c\/li\u003e\n\u003cli\u003eGalvanized steel construction provides corrosion resistance for long service life\u003c\/li\u003e\n\u003cli\u003eOverall height of 7 inches accommodates standard joist bay depth requirements\u003c\/li\u003e\n\u003cli\u003eSold individually, compatible with standard sheet metal screws and mastic or foil-tape sealing methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-construction fitting for residential and light commercial forced-air duct systems requiring a 6-inch round to 2.25-inch by 10-inch rectangular transition at a 90-degree stack boot position.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal installer. Shut down the air handling unit and confirm the system is de-energized before connecting or sealing any duct section. Secure the boot to the round duct with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape in accordance with applicable mechanical codes. Do not rely on duct tape alone for sealing supply air connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Width\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 7 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: 0.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 57521061\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692033245490,"sku":"57521061","price":25.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f833de5f01d2c3049e6e57f91c386d2_ca65272b-5494-4717-8cd4-b96191c9f573.jpg?v=1788292222","url":"https:\/\/voomisupply.com\/products\/value-collection-57521061-galvanized-90-deg-stack-boot-6-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
