This sheet metal boot is used in forced-air HVAC systems to redirect airflow from round trunk or branch lines into oval end-boot connections at registers or grilles. The crimped end allows the fitting to slide directly into the next section of ductwork without additional tooling. HVAC sheet metal technicians and installers use this fitting during new construction and retrofit duct fabrication work.\u003c\/p\u003e\n\u003cp\u003eThis boot is suited for residential and light commercial forced-air systems where round-to-oval transitions are required at the end of a duct run. The 90-degree offset makes it practical in tight ceiling or wall cavities where a straight boot will not fit. It is a standard component in supply-air duct systems installed by licensed HVAC contractors and sheet metal workers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions 7-inch round duct to 7-inch oval in a single fitting\u003c\/li\u003e\n  \u003cli\u003e90-degree end boot configuration for tight-space installations\u003c\/li\u003e\n  \u003cli\u003eCrimped end for tool-free slip-fit connection to adjacent ductwork\u003c\/li\u003e\n  \u003cli\u003eSheet metal construction for durability in forced-air supply applications\u003c\/li\u003e\n  \u003cli\u003eStandard sizing compatible with common residential duct layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction fitting for residential and light commercial forced-air HVAC duct systems requiring a 7-inch round to 7-inch oval 90-degree end boot transition.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or sheet metal workers. Power down the air handling system before modifying any duct section. Secure all joints with approved sheet metal screws and seal with UL 181-rated mastic or foil tape per local mechanical code requirements. Do not compress or restrict the oval outlet opening during installation, as this will reduce airflow to the connected register.\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\u003eAngle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Crimped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e: 35.25 inches\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: OB7107CO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LUKJAN","offers":[{"title":"Default Title","offer_id":51506797117746,"sku":"OB7107CO","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/SEALTITE4244.gif?v=1784931038","url":"https:\/\/voomisupply.com\/products\/lukjan-ob7107co-7-in-round-to-oval-90-degree-end-boot","provider":"Voomi Supply","version":"1.0","type":"link"}
