Fabricated from hot dip galvanized steel, this elbow maintains an 18 x 10 inch cross-section on both the inlet and outlet, making it a true same-size fitting with no reduction in airflow area. The radius throat geometry supports smoother airflow transitions through the turn compared to square-throat alternatives. This fitting is installed by licensed HVAC technicians and sheet metal mechanics during new construction ductwork runs or duct replacement projects.\u003c\/p\u003e\n\u003cp\u003eThe 14_18X10 is suited for residential and light commercial forced-air HVAC systems where trunk duct routing requires a 90-degree directional change. Its flat Broadway profile is commonly used in low-clearance installations such as crawlspaces, attic runs, and tight mechanical rooms where a standard radius elbow would not fit. The consistent 18 x 10 inch sizing on both ends allows direct connection to existing rectangular trunk duct sections without transitions or reducers. Applications are governed by ACCA and SMACNA standards for duct construction and installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree angle for right-angle trunk duct routing\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in HVAC environments\u003c\/li\u003e\n  \u003cli\u003eFlat Broadway style profile for use in low-clearance installations\u003c\/li\u003e\n  \u003cli\u003eRadius throat design promotes smoother airflow through the bend\u003c\/li\u003e\n  \u003cli\u003eConsistent 18 x 10 inch sizing on both inlet and outlet — no reduction fitting required\u003c\/li\u003e\n  \u003cli\u003eMeets 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 sheet metal fitting for rectangular trunk duct systems requiring a 90-degree elbow at an 18 x 10 inch duct size, installed per ACCA and SMACNA ductwork standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or sheet metal mechanic. Shut down the air handling system and lock out power before cutting into or connecting to an existing duct run. Secure the elbow with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA guidelines. Confirm that the fitting orientation matches the intended airflow direction before fastening.\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: Flat, Broadway, Radius Throat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A (Inlet)\u003c\/strong\u003e: 18 x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B (Outlet)\u003c\/strong\u003e: 18 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: 14_18X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284019773746,"sku":"14_18X10","price":86.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277372.jpg?v=1781066235","url":"https:\/\/voomisupply.com\/products\/southwark-metal-14_18x10-trunk-duct-elbow-18x10-in-90-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
