Fabricated from hot dip galvanized steel, this collar provides a secure, corrosion-resistant transition point where branch takeoffs connect to the main trunk duct. At 26 inches by 10 inches, it fits standard rectangular duct openings and is built to ACCA and SMACNA standards. HVAC sheet metal mechanics and ductwork fabricators install this fitting during new construction or duct retrofit projects requiring a clean, code-compliant trunk connection.\u003c\/p\u003e\n\u003cp\u003eThis starting collar is used in residential and light commercial forced-air systems where a main trunk duct requires a straight takeoff connection point. It is suited for supply-air trunk duct assemblies installed in attics, crawlspaces, mechanical rooms, and conditioned utility areas. The straight body pattern simplifies layout and reduces pressure drop at the trunk connection. Installers working to SMACNA duct construction standards will find this collar consistent with rectangular duct fabrication requirements for low- and medium-pressure systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in typical HVAC environments\u003c\/li\u003e\n  \u003cli\u003eStraight body pattern for direct, low-restriction trunk duct connections\u003c\/li\u003e\n  \u003cli\u003eStarting collar type for initiating branch takeoff at the trunk\u003c\/li\u003e\n  \u003cli\u003e26 inch by 10 inch opening sized for standard rectangular duct systems\u003c\/li\u003e\n  \u003cli\u003eManufactured to 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 assemblies in residential and light commercial forced-air HVAC systems requiring a 26 inch by 10 inch straight starting collar.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down the air handling system and lock out the power supply before cutting into or modifying any duct section. Secure the collar to the trunk duct using drive cleats, S-cleats, or sheet metal screws per SMACNA duct construction standards, and seal all joints with UL 181-listed mastic or foil tape to meet local mechanical code requirements. Do not use this fitting as a structural support for other duct sections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 26 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\u003eBody Pattern\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Starting\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: 20_26X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284121354546,"sku":"20_26X10","price":47.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277170.jpg?v=1781069044","url":"https:\/\/voomisupply.com\/products\/southwark-metal-20_26x10-trunk-duct-collar-26x10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
