Built from hot dip galvanized steel, this fitting offers a shortway, vertical, radius throat configuration that directs airflow through a tight turn while minimizing turbulence and pressure drop. The radius throat geometry is preferred in applications where space constraints require a compact elbow footprint without sacrificing airflow efficiency. HVAC sheet metal technicians and duct fabricators install this fitting during new construction and retrofit projects where trunk duct routing must change direction within a confined mechanical space.\u003c\/p\u003e\n\u003cp\u003eThis elbow is sized 18 inches by 10 inches on both the inlet and outlet faces, making it a same-size transition fitting with no cross-sectional change through the turn. It is suited for low-pressure forced-air supply and return trunk systems in residential and light commercial settings. The shortway orientation reduces the overall installed depth of the elbow compared to a longway fitting, which is useful when working in tight plenum or attic spaces. Fabricated to ACCA and SMACNA standards, this fitting meets the dimensional and material requirements expected in code-compliant duct installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in typical HVAC duct environments\u003c\/li\u003e\n  \u003cli\u003e90-degree angle for a full right-angle direction change in trunk duct routing\u003c\/li\u003e\n  \u003cli\u003eShortway, vertical, radius throat design reduces installed depth and limits turbulence\u003c\/li\u003e\n  \u003cli\u003eSame inlet and outlet size: 18 inches by 10 inches on both ends\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards for code-compliant duct systems\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 rectangular trunk duct systems requiring a 90-degree shortway elbow at 18 inches by 10 inches duct size, in accordance with 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 mechanic. Power down the air handling unit and confirm the system is de-energized before accessing the duct system. Seal all joints with approved duct sealant or mastic and secure with sheet metal screws per SMACNA guidelines to meet energy code requirements. Do not modify the radius throat geometry, as alterations can introduce turbulence and reduce system efficiency.\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\u003eAngle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Shortway, Vertical, Radius Throat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A (Inlet)\u003c\/strong\u003e: 18 inches x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B (Outlet)\u003c\/strong\u003e: 18 inches x 10 inches\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: 16_18X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283914588466,"sku":"16_18X10","price":68.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277335.jpg?v=1781063141","url":"https:\/\/voomisupply.com\/products\/southwark-metal-16_18x10-trunk-duct-elbow-18x10-shortway","provider":"Voomi Supply","version":"1.0","type":"link"}
