Fabricated from hot-dipped galvanized steel, this boot transitions a 3-1\/4 inch by 14 inch rectangular wall stack opening to an 8-inch round duct collar. The 90-degree elbow configuration makes it the standard choice for floor-to-wall or ceiling-to-wall transitions in forced-air supply duct layouts. HVAC sheet metal installers and duct fabricators use this fitting to terminate stub-out supply runs at registers and diffusers. Compliance with ACCA and SMACNA standards confirms the fitting meets recognized industry fabrication and performance benchmarks.\u003c\/p\u003e\n\u003cp\u003eThis wall stack elbow boot is suited for residential new construction and retrofit forced-air heating and cooling systems where space constraints require a 90-degree offset between the supply trunk or branch and the wall cavity stack. Typical installations include interior wall stack supplies feeding floor or baseboard registers. The rectangular inlet fits standard 3-1\/4 inch by 14 inch wall cavity duct runs, while the 8-inch round outlet connects to flexible or rigid round duct. No specific model-family compatibility was stated in the product data.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dipped galvanized steel construction resists corrosion in supply air duct environments\u003c\/li\u003e\n  \u003cli\u003e90-degree elbow geometry transitions from wall stack to horizontal or vertical duct run\u003c\/li\u003e\n  \u003cli\u003eRectangular inlet measures 3-1\/4 inches by 14 inches to fit standard wall cavity stacks\u003c\/li\u003e\n  \u003cli\u003e8-inch round outlet accommodates standard flexible or rigid round duct collars\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct fittings\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 and light commercial forced-air supply duct systems using 3-1\/4 inch by 14 inch rectangular wall stacks transitioning to 8-inch round duct.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handling system and confirm the system is de-energized before cutting into existing ductwork or sealing new connections. Seal all joints with UL 181-listed duct mastic or approved metal foil tape per local mechanical code requirements. Follow SMACNA duct construction standards and applicable local codes for support spacing and fastener requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dipped Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size (Size A)\u003c\/strong\u003e: 3-1\/4 inches x 14 inches (rectangular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size (Size B)\u003c\/strong\u003e: 8 inches diameter (round)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Stack, 90 Degree, Rectangular to Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\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: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 24_3-1\/4X14X8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284052017458,"sku":"24_3-1\/4X14X8","price":32.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277057.jpg?v=1781067225","url":"https:\/\/voomisupply.com\/products\/southwark-metal-24_3-1-4x14x8-duct-wall-stack-boot","provider":"Voomi Supply","version":"1.0","type":"link"}
