Fabricated from hot dip galvanized steel, this boot resists corrosion in the humid, high-cycle environments common to residential and light commercial HVAC systems. It is installed by licensed HVAC technicians as part of a forced-air supply or return distribution system, typically where ductwork runs through wall cavities to serve floor or wall registers.\u003c\/p\u003e\n\u003cp\u003eThis straight wall stack boot is suited for new construction and retrofit applications where a rectangular trunk or branch duct must connect to a round 6 inch take-off or register collar within a wall stack configuration. The 3-1\/4 inch by 12 inch face dimension is a standard size for high-velocity, space-constrained wall cavities in residential forced-air systems. Installers working to ACCA and SMACNA standards will find this fitting designed to meet those applicable guidelines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in humid duct environments\u003c\/li\u003e\n  \u003cli\u003eStraight wall stack configuration for direct rectangular-to-round transitions\u003c\/li\u003e\n  \u003cli\u003e3-1\/4 inch by 12 inch rectangular inlet matches standard wall cavity duct sizing\u003c\/li\u003e\n  \u003cli\u003e6 inch round collar outlet for connection to standard round duct or register boots\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards\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 HVAC duct systems requiring a straight wall stack boot with a 3-1\/4 inch by 12 inch rectangular opening and a 6 inch round outlet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with ACCA Manual D duct design guidelines and applicable SMACNA standards. Shut down the air handling unit and verify the system is de-pressurized before cutting into existing ductwork or connecting this fitting. Secure all seams with listed duct sealant or UL 181-rated tape per local mechanical code requirements. Do not compress or over-bend the collar during installation, as deformation can restrict airflow and affect system balance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size (Size A)\u003c\/strong\u003e: 3.25 inches x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size (Size B)\u003c\/strong\u003e: 6 inch diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Wall Stack, Straight\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: 27_3-1\/4X12X6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284017414450,"sku":"27_3-1\/4X12X6","price":18.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277033.jpg?v=1781066176","url":"https:\/\/voomisupply.com\/products\/southwark-metal-27_3-1-4x12x6-duct-boot-wall-stack","provider":"Voomi Supply","version":"1.0","type":"link"}
