Fabricated from hot dip galvanized steel, this wall stack measures 3.25 inches by 12 inches by 24 inches and is built to meet the dimensional and performance standards set by ACCA and SMACNA. HVAC installers and sheet metal contractors use this fitting to transition ductwork through wall cavities, delivering conditioned air to floor-level or wall-mounted registers. The galvanized steel construction resists corrosion and holds up in both supply and return air applications.\u003c\/p\u003e\u003cp\u003eWall stack fittings like the WSJ_24X3-1\/4X12 are a standard component in forced-air heating and cooling systems found in residential new construction and retrofit projects. The 3.25 by 12 inch cross-section fits standard wall cavity dimensions and connects to floor-to-wall transitions feeding baseboard or floor registers. This fitting is typically installed by licensed HVAC technicians or sheet metal mechanics during rough-in or system modification work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot dip galvanized steel construction for corrosion resistance in supply and return air applications\u003c\/li\u003e\n\u003cli\u003e3.25 x 12 x 24 inch dimensions sized for standard residential wall cavity installations\u003c\/li\u003e\n\u003cli\u003eMeets ACCA and SMACNA applicable standards for duct fabrication and installation\u003c\/li\u003e\n\u003cli\u003eRectangular profile compatible with standard wall stack register boots and duct transitions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for residential forced-air duct systems requiring a 3.25 x 12 x 24 inch wall stack configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eWall stack duct fittings are installed by licensed HVAC technicians or sheet metal mechanics. Shut down the air handling system and ensure the system is de-energized before modifying or connecting ductwork. Seams and joints should be sealed with UL-listed duct mastic or metal foil tape in accordance with SMACNA installation guidelines. Follow local mechanical codes for support spacing and clearance requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\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: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 24 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_24X3-1\/4X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283915145522,"sku":"WSJ_24X3-1\/4X12","price":23.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277045.jpg?v=1781063152","url":"https:\/\/voomisupply.com\/products\/southwark-metal-wsj_24x3-1-4x12-duct-wall-stack","provider":"Voomi Supply","version":"1.0","type":"link"}
