This fitting provides a smooth, radius-style directional change rather than a sharp square-throat turn, reducing static pressure loss and turbulence at the elbow. It measures 14 x 12 x 8 inches and is fabricated from sheet metal to standard HVAC duct construction practices. HVAC sheet metal mechanics and duct fabricators install this fitting during new construction and retrofit projects requiring a 90-degree directional change in low-pressure supply or return air distribution systems.\u003c\/p\u003e\u003cp\u003eThis radius elbow is suited for residential and light commercial HVAC duct systems where maintaining airflow efficiency through directional transitions is a priority. The flat profile accommodates installations in confined ceiling plenums, crawlspaces, or between-joist runs where a standard round or high-profile elbow would not fit. It connects inline with rectangular ductwork at the specified 14 x 12 x 8 inch dimensions and is fabricated for field assembly or pre-fabricated system integration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRadius-style 90-degree turn reduces turbulence and static pressure drop compared to square-throat elbows\u003c\/li\u003e\n\u003cli\u003eFlat elbow profile fits low-clearance installation spaces such as ceiling plenums and crawlspaces\u003c\/li\u003e\n\u003cli\u003eSheet metal construction compatible with standard rectangular duct assembly methods\u003c\/li\u003e\n\u003cli\u003e14 x 12 x 8 inch dimensions for direct integration into matching rectangular duct runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sheet metal duct fitting for rectangular low-pressure HVAC supply and return air distribution systems requiring a 90-degree directional change.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed sheet metal mechanics or HVAC technicians following SMACNA duct construction standards. Shut down the air handling unit and de-energize associated equipment before beginning ductwork modifications. Secure the fitting to adjoining duct sections using standard drive cleats, S-cleats, or mechanical fasteners, and seal all joints with UL 181-rated mastic or approved foil tape per local mechanical code requirements.\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\u003eDimensions\u003c\/strong\u003e: 14 x 12 x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Sheet Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Shape\u003c\/strong\u003e: Rectangular\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: 1146R128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51344005595442,"sku":"1146R128","price":57.89,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555282.jpg?v=1782026642","url":"https:\/\/voomisupply.com\/products\/southwark-metal-1146r128-flat-90-radius-elbow-14x12x8","provider":"Voomi Supply","version":"1.0","type":"link"}
