Fabricated from hot dip galvanized steel, this elbow measures 3-1\/4 inches by 10 inches on both the inlet and outlet ends, making it a true same-size transition fitting. The flat, Broadway, longway configuration suits narrow wall cavity installations where standard round or deep elbows will not fit. Licensed HVAC technicians and sheet metal installers use this fitting when routing low-profile supply duct through interior walls and floor systems.\u003c\/p\u003e\n\u003cp\u003eThis elbow is a standard component in residential forced-air distribution systems, particularly in wall stack applications where duct depth is limited to 3-1\/4 inches. It is suited for new construction and retrofit installations where supply air must make a 90-degree directional change within a framed wall cavity. The Broadway and longway orientation directs airflow along the long dimension of the rectangular duct cross-section, helping maintain velocity pressure through the turn. ACCA and SMACNA standards govern its application in duct system design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree elbow angle for right-angle duct direction changes\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in occupied building cavities\u003c\/li\u003e\n  \u003cli\u003eFlat, Broadway, longway profile fits 3-1\/4 inch wall stack duct runs\u003c\/li\u003e\n  \u003cli\u003eConsistent 3-1\/4 inch by 10 inch opening on both ends — no reducing transition required\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct fabrication and installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for 3-1\/4 inch by 10 inch rectangular wall stack duct systems in residential forced-air HVAC installations built to ACCA and SMACNA standards.\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 worker in accordance with local mechanical codes and SMACNA duct construction guidelines. Power down the air handler and close the supply air damper before working on the duct system. Secure all joints with sheet metal screws and seal with UL 181-listed mastic or approved foil tape to meet code air-leakage requirements. Do not use this fitting in applications requiring a reducing elbow — size inlet and outlet duct to match the 3-1\/4 inch by 10 inch opening on both sides.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A\u003c\/strong\u003e: 3-1\/4 inches x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B\u003c\/strong\u003e: 3-1\/4 inches x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Flat, Broadway, Longway, Wall Stack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\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: WS14_3-1\/4X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284047855922,"sku":"WS14_3-1\/4X10","price":36.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277103.jpg?v=1781067145","url":"https:\/\/voomisupply.com\/products\/southwark-metal-ws14_3-1-4x10-duct-elbow-90-degree-3-1-4x10","provider":"Voomi Supply","version":"1.0","type":"link"}
