It includes 16-inch rails that position the boot and support the register during installation. This fitting serves as the transition point between the supply duct run and the floor or ceiling register opening. HVAC installers use it to direct conditioned air from a rectangular duct into the occupied space through a standard register. The elbow geometry accommodates installations where the duct approaches the register from a horizontal run into a vertical drop or rise.\u003c\/p\u003e\n\u003cp\u003eThis boot is suited for residential HVAC systems where supply air is distributed through basement ceilings or overhead ceiling applications. The 4-inch by 12-inch throat matches standard rectangular duct sizes common in residential forced-air systems. The included 16-inch rails extend the boot to span typical joist bays or framing cavities, simplifying rough-in and register placement during new construction or retrofit work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch by 12-inch by 7-inch elbow geometry for horizontal-to-vertical duct transitions\u003c\/li\u003e\n  \u003cli\u003eIncludes 16-inch rails for spanning joist bays and securing register placement\u003c\/li\u003e\n  \u003cli\u003eDesigned for basement ceiling and overhead ceiling register applications\u003c\/li\u003e\n  \u003cli\u003eFits standard 4-inch by 12-inch rectangular supply duct connections\u003c\/li\u003e\n  \u003cli\u003eElbow profile directs airflow from horizontal duct runs into vertical register openings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-construction fitting for residential forced-air systems using 4-inch by 12-inch rectangular supply ductwork with standard ceiling or basement register configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal installer. Shut down the air handler and confirm the system is de-energized before working on supply duct connections. Secure the boot to framing members using the included rails and fasten duct connections with appropriate sheet metal screws and mastic sealant or UL-listed foil tape per local mechanical code requirements. Do not operate the system until all duct connections are fully sealed and the register is properly seated.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThroat Size\u003c\/strong\u003e: 4 x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoot Depth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRail Length\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoot Type\u003c\/strong\u003e: Elbow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Basement and Ceiling Register\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: 1279-041207\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SEAL-TITE","offers":[{"title":"Default Title","offer_id":51345466655026,"sku":"1279-041207","price":38.03,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554897.jpg?v=1782059156","url":"https:\/\/voomisupply.com\/products\/seal-tite-1279-041207-elbow-register-boot-4x12x7-in-with-rails","provider":"Voomi Supply","version":"1.0","type":"link"}
