This 59F-style boot connects round duct to a rectangular floor or sidewall register opening, with a 5 inch collar for round duct attachment and a 4 inch by 10 inch register boot face. The insulated construction reduces heat loss and condensation along the boot body, making it suitable for installations in unconditioned spaces such as crawlspaces, basements, and floor cavities. HVAC installers and sheet metal mechanics use this fitting during new construction and retrofit duct runs.\u003c\/p\u003e\u003cp\u003eThis boot is used in residential forced-air heating and cooling systems where a transition from round supply duct to a rectangular register opening is required. The short top configuration is suited for applications with limited plenum or floor joist depth. The fixed flange simplifies register mounting and provides a clean finished appearance at the register face. This fitting is appropriate for floor, sidewall, or low-sidewall register installations depending on system layout.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eShort top profile for installations with limited vertical clearance\u003c\/li\u003e\n\u003cli\u003eInsulated body reduces heat loss and limits condensation in unconditioned spaces\u003c\/li\u003e\n\u003cli\u003eIntegrated flange provides a secure register mounting surface\u003c\/li\u003e\n\u003cli\u003e5 inch round collar for connection to standard round flex or rigid supply duct\u003c\/li\u003e\n\u003cli\u003e4 inch by 10 inch boot face matches common residential register sizes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting compatible with standard 4 inch by 10 inch floor or sidewall registers and 5 inch round supply duct in residential forced-air HVAC systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down the air handling unit and confirm the system is de-energized before connecting or sealing ductwork at this fitting. Seal all duct joints with listed mastic or UL 181-rated tape per local mechanical code requirements. Do not compress or kink flexible duct at the collar connection, as this restricts airflow and reduces system efficiency.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoot Face Size\u003c\/strong\u003e: 4 x 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoot Style\u003c\/strong\u003e: Short Top with Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 59F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AIR FLOW PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 59041005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51345459872050,"sku":"59041005","price":39.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554491.jpg?v=1782058915","url":"https:\/\/voomisupply.com\/products\/air-flow-products-59041005-insulated-boot-flange-4x10-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
