Fabricated from hot-dipped galvanized steel, this fitting transitions a 3-1\/4 inch by 10 inch rectangular duct opening to a 7 inch round collar at a 90-degree angle. It is installed where a trunk or branch duct run turns to supply a wall register or floor boot. HVAC sheet metal mechanics and duct installers work with this fitting during new construction and retrofit duct system projects. The galvanized steel construction provides corrosion resistance suitable for conditioned-air supply and return applications.\u003c\/p\u003e\n\u003cp\u003eThis boot fitting is used in residential and light commercial forced-air duct systems where a wallstack configuration is required. The 90-degree angle allows the duct to transition from a horizontal trunk line or branch run into a vertical wall cavity leading to a register. The 3-1\/4 inch by 10 inch rectangular face matches standard wallstack and floor register dimensions commonly found in residential new construction. The 7 inch round collar connects to round branch duct or spiral pipe of the corresponding diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree rectangular-to-round transition for wallstack elbow installations\u003c\/li\u003e\n  \u003cli\u003eRectangular face measures 3-1\/4 inches by 10 inches to match standard register openings\u003c\/li\u003e\n  \u003cli\u003e7 inch round collar for connection to round branch duct or spiral pipe\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized steel construction for corrosion resistance in conditioned-air systems\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 duct fitting for residential and light commercial forced-air HVAC duct systems requiring a 3-1\/4 inch by 10 inch rectangular to 7 inch round 90-degree wallstack boot transition.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics following SMACNA and ACCA duct construction standards. Power down the air handling unit and verify the system is de-energized before working in the duct system. Seal all joints with UL 181-rated mastic or foil tape per local mechanical code requirements. Do not overtighten sheet metal screws at the collar connection, as this can deform the round collar and compromise the duct seal.\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\u003eRectangular Face Size (Size A)\u003c\/strong\u003e: 3-1\/4 inches x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRound Collar Diameter (Size B)\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Stack, Rectangular to Round Elbow Boot\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\/4X10X7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284120600882,"sku":"24_3-1\/4X10X7","price":21.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277050.jpg?v=1781069025","url":"https:\/\/voomisupply.com\/products\/southwark-metal-24_3-1-4x10x7-duct-wallstack-elbow-boot","provider":"Voomi Supply","version":"1.0","type":"link"}
