This fitting makes a smooth 90-degree directional change in a low-profile, flat orientation, helping route supply or return air through tight ceiling, wall, or floor cavities where a standard throat elbow will not fit. The radius design reduces turbulence at the turn compared to a sharp-throat fitting, supporting better airflow efficiency through the duct system. Sheet metal contractors and HVAC installers use this fitting in new construction and retrofit duct systems.\u003c\/p\u003e\u003cp\u003eThis elbow is sized for 20x10 inch rectangular duct and is suited for residential and light commercial forced-air HVAC systems. The flat geometry makes it particularly useful in low-clearance applications such as under-floor installations, dropped ceiling spaces, and horizontal trunk-line routing where vertical depth is limited. It connects inline with standard rectangular sheet metal duct sections of matching cross-section.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlat 90-degree radius turn for low-clearance duct routing\u003c\/li\u003e\n\u003cli\u003eRadius construction reduces airflow resistance at the elbow compared to square-throat designs\u003c\/li\u003e\n\u003cli\u003eSized for 20x10 inch rectangular ductwork\u003c\/li\u003e\n\u003cli\u003eSheet metal construction suitable for standard forced-air duct systems\u003c\/li\u003e\n\u003cli\u003eCompatible with standard rectangular duct slip or drive connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sheet metal duct fitting for use with standard 20x10 inch rectangular duct sections in residential and light commercial forced-air HVAC duct systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed sheet metal contractor or HVAC technician in accordance with SMACNA duct construction standards and applicable local mechanical codes. Disconnect and lock out the air handling unit before working on the duct system. Secure the fitting to adjoining duct sections using drive cleats, S-cleats, or equivalent fasteners, and seal all joints with UL 181-rated mastic or foil tape to maintain system integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Flat 90-Degree Radius Elbow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 20x10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Sheet Metal\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: 1146R2010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51347528483122,"sku":"1146R2010","price":129.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555348.jpg?v=1782107700","url":"https:\/\/voomisupply.com\/products\/southwark-metal-1146r2010-flat-90-radius-elbow-20x10","provider":"Voomi Supply","version":"1.0","type":"link"}
