This fitting transitions airflow from a round duct collar to an oval duct run in a straight-line configuration. The crimped end allows it to slip directly into an adjoining duct section without additional fasteners during initial fit-up. HVAC sheet metal installers and duct fabricators use this boot where round supply or return duct lines need to connect to oval duct runouts in residential and light commercial systems.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for new construction and retrofit duct installations where space constraints favor oval duct runs off a round main. The straight boot orientation keeps the transition direct and compact, making it a common choice in tight ceiling, crawlspace, and wall cavity applications. Sheet metal contractors and HVAC installers typically use this component during rough-in work when laying out trunk-and-branch or radial duct systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch round inlet transitions to a 7-inch oval outlet in a straight configuration\u003c\/li\u003e\n  \u003cli\u003eCrimped end allows for quick slip-fit connection into adjoining duct sections\u003c\/li\u003e\n  \u003cli\u003eStraight boot orientation supports compact, direct duct routing in confined spaces\u003c\/li\u003e\n  \u003cli\u003eSized for residential and light commercial HVAC duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for residential and light commercial HVAC duct systems using 7-inch round-to-oval straight boot configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal workers. Power down the air handling unit and close the system dampers before making duct connections. Secure the boot to adjoining duct sections with sheet metal screws and seal all joints with UL 181-rated duct sealant or approved foil tape per local mechanical code requirements. Do not compress or deform the oval outlet during installation, as this will restrict airflow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRound Inlet Size\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOval Outlet Size\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoot Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Crimped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: HVAC Duct Fittings\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: LUKJAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: OB7207CO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LUKJAN","offers":[{"title":"Default Title","offer_id":51306609279282,"sku":"OB7207CO","price":15.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549012.jpg?v=1781293253","url":"https:\/\/voomisupply.com\/products\/lukjan-ob7207co-7-in-round-to-oval-straight-boot-crimp","provider":"Voomi Supply","version":"1.0","type":"link"}
