Constructed from hot dip galvanized steel, it provides a durable, corrosion-resistant transition point in supply or return trunk lines. The shortway vertical configuration with a radius throat minimizes turbulence and pressure drop through the turn. Both the inlet and outlet measure 20 inches by 10 inches, making this a same-size elbow with no transition offset. Sheet metal contractors and HVAC installers use this fitting when routing trunk duct around structural obstructions or making directional changes in tight vertical spaces.\u003c\/p\u003e\n\u003cp\u003eThis elbow is suited for residential and light commercial forced-air HVAC installations where galvanized steel trunk ductwork is specified. The shortway orientation is chosen when horizontal clearance is limited and the fitting must change direction within a reduced footprint. The radius throat design supports smoother airflow compared to square-throat fittings, reducing static pressure loss along the duct run. Fabricated to ACCA and SMACNA standards, this fitting is appropriate for systems designed and installed to meet current industry specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree elbow angle for right-angle trunk duct routing\u003c\/li\u003e\n  \u003cli\u003eShortway vertical configuration for installations with limited horizontal clearance\u003c\/li\u003e\n  \u003cli\u003eRadius throat design reduces turbulence and static pressure loss through the turn\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eSame-size inlet and outlet at 20 inches by 10 inches — no transition required\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for rectangular galvanized steel trunk duct systems sized at 20 inches by 10 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSheet metal contractors and licensed HVAC technicians typically install trunk duct elbows as part of a forced-air distribution system. Power down the air handling equipment and verify the system is depressurized before making connections to existing ductwork. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA installation guidelines. Handle cut edges with care — galvanized sheet metal edges are sharp and appropriate work gloves should be worn throughout installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Duct Elbow\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\u003c\/strong\u003e: 20 inches x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B\u003c\/strong\u003e: 20 inches x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\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_20X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284111294770,"sku":"16_20X10","price":72.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277332.jpg?v=1781068802","url":"https:\/\/voomisupply.com\/products\/southwark-metal-16_20x10-trunk-duct-elbow-20x10-in-90-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
