Measuring 100 inches in length, 3.25 inches in width, and 14 inches in height, it provides a low-profile rectangular duct run designed to fit within standard wall cavities. The hot dip galvanized steel construction resists corrosion and meets ACCA and SMACNA fabrication standards. HVAC sheet metal installers and mechanical contractors use this component as part of supply or return air duct systems where space constraints require a wall-stack configuration.\u003c\/p\u003e\u003cp\u003eWall stack duct sections like the WSJ_3-1\/4X14X100 are commonly installed in interior wall cavities to route conditioned air between floors or to serve register boots at floor or ceiling level. The slim 3.25-inch width allows installation in standard 2x4 framed walls without modification. This product is suited for new construction and retrofit applications in residential settings where conventional round or rectangular trunk duct cannot be routed through framing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot dip galvanized steel construction for corrosion resistance in interior duct applications\u003c\/li\u003e\n\u003cli\u003e100-inch length reduces the number of joints required in tall wall runs\u003c\/li\u003e\n\u003cli\u003e3.25-inch width fits within standard 2x4 stud cavities\u003c\/li\u003e\n\u003cli\u003eFabricated to ACCA and SMACNA applicable standards\u003c\/li\u003e\n\u003cli\u003eRectangular profile accommodates wall stack fittings, boots, and transitions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sheet metal wall stack section compatible with standard ACCA- and SMACNA-compliant forced-air duct systems using 3.25-inch by 14-inch wall stack configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eWall stack duct sections are installed by licensed HVAC technicians or sheet metal mechanics following SMACNA duct construction standards and local mechanical codes. Power down the air handling system before cutting into or connecting duct sections. Seal all joints with UL 181-listed mastic or approved foil tape to meet energy code requirements. Avoid kinking or deforming the duct profile during handling, as dimensional distortion will affect fitting connections and airflow performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dipped Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: WSJ_3-1\/4X14X100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284030783794,"sku":"WSJ_3-1\/4X14X100","price":83.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277038.jpg?v=1781066621","url":"https:\/\/voomisupply.com\/products\/southwark-metal-wsj_3-1-4x14x100-sheet-metal-wall-stack","provider":"Voomi Supply","version":"1.0","type":"link"}
