Fabricated from 26-gauge galvanized sheet metal, this fitting attaches directly to flat duct board or sheet metal plenums using a peel-off adhesive backing, eliminating the need for mechanical fasteners during initial attachment. The 5-inch twist-lock collar features a hemmed edge, an engineered throat and radii for improved airflow transition, and a fully closed corner with a double-lapped, mechanically seamed joint for added structural integrity. Licensed HVAC technicians and sheet metal mechanics use this fitting to branch supply air from trunk ducts or air handler plenums.\u003c\/p\u003e\n\u003cp\u003eThe 301-05 is suited for trunk-and-branch duct systems in residential new construction and retrofit applications. The peel-off adhesive simplifies placement on duct board plenums, while the hemmed 5-inch collar accepts standard round duct and flex duct connectors. This fitting is commonly installed at the plenum face where individual branch runs originate, providing a clean, sealed transition point. Its construction meets the requirements of several widely referenced energy and mechanical codes and standards applicable to forced-air duct system assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePeel-off adhesive backing for direct attachment to duct board or sheet metal plenums without additional fasteners\u003c\/li\u003e\n  \u003cli\u003e26-gauge galvanized sheet metal construction for corrosion resistance and rigidity\u003c\/li\u003e\n  \u003cli\u003eHemmed collar edge reduces sharp edges and provides a secure fit for round duct connections\u003c\/li\u003e\n  \u003cli\u003eEngineered throat and radii promote smooth airflow transition into the branch run\u003c\/li\u003e\n  \u003cli\u003eFully closed corner with double-lapped, mechanically seamed joint for structural integrity and air sealing\u003c\/li\u003e\n  \u003cli\u003eMeets CCR\/Title 24, IECC, HARDI, ACCA, AHREXPO, and ADI 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 use with 5-inch round duct and flex duct branch connections in forced-air supply duct systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed sheet metal mechanic or HVAC technician. Shut down the air handler and confirm the system is de-energized before cutting into any existing plenum or duct surface. Ensure the plenum surface is clean and free of debris before applying the adhesive backing to achieve a proper seal. Supplement with mastic sealant or UL 181-rated tape at the collar joint as required by local mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Type\u003c\/strong\u003e: Round, Twist\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Thickness\u003c\/strong\u003e: 26 Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\/Model\u003c\/strong\u003e: 301\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: CCR\/Title 24, IECC, HARDI, ACCA, AHREXPO, ADI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInclusions\/Features\u003c\/strong\u003e: Peel Off Adhesive, Hemmed Collar, Fully Closed Corner, Engineered Throat and Radii, Double Lapped, Mechanically Seamed Corner and Joint\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: SEAL-TITE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 301-05\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SEAL-TITE","offers":[{"title":"Default Title","offer_id":51347248939314,"sku":"301-05","price":17.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554557.jpg?v=1782100266","url":"https:\/\/voomisupply.com\/products\/seal-tite-301-05-stick-on-takeoff-collar-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
