The fitting measures 3.25 inches by 10 inches at the rectangular end and accepts a 6-inch round collar, making it a standard choice for floor or wall stack installations where supply air is routed from a main trunk or plenum to a floor register boot. The 90-degree elbow geometry allows the duct run to turn at a right angle within tight framing cavities. Galvanized steel construction resists moisture and corrosion in typical forced-air applications.\u003c\/p\u003e\n\u003cp\u003eThis stack boot is used in new construction and replacement duct work for residential forced-air heating and cooling systems. It fits between the subfloor framing and connects a horizontal or vertical sheet metal duct run to a floor register. HVAC installers and sheet metal contractors use this fitting when running supply ducts through floor joists or wall cavities where a 90-degree transition from a flat rectangular duct to a round collar is required. The 6-inch collar diameter accommodates standard 6-inch round flex or rigid duct.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree elbow geometry for right-angle duct transitions in floor or wall stack applications\u003c\/li\u003e\n  \u003cli\u003e3.25 x 10 inch rectangular opening matches standard trunk and plenum take-off sizes\u003c\/li\u003e\n  \u003cli\u003e6-inch round collar connects to standard 6-inch flex or rigid round duct\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction provides corrosion resistance for long-term duct integrity\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.5 pounds for easy handling during installation in tight framing spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for residential forced-air HVAC duct systems requiring a 3.25 x 10 inch rectangular to 6-inch round 90-degree stack boot transition.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling unit and close the system dampers before modifying any duct section. Secure the rectangular collar to the trunk or plenum take-off with sheet metal screws and seal all joints with UL-listed duct mastic or metal-backed tape per local mechanical code requirements. Do not use standard cloth duct tape as a primary sealant.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size (Rectangular)\u003c\/strong\u003e: 3.25 x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElbow Degree\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: 90 Stack Boot\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: 0.5 pounds\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: SNAPPY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13-306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SNAPPY","offers":[{"title":"Default Title","offer_id":51233296941362,"sku":"13-306","price":22.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307630021.jpg?v=1780096604","url":"https:\/\/voomisupply.com\/products\/snappy-13-306-90-stack-boot-3-25x10-in-6-in-collar","provider":"Voomi Supply","version":"1.0","type":"link"}
