It measures 4 inches by 10 inches at the main body with a 6-inch neck and includes a 2-inch extension, making it suitable for tight or offset duct-to-register connections. Left end boots are used where the supply register sits at the end of a duct run and the connection must exit from the left side. HVAC installers and sheet metal contractors use this fitting when laying out trunk-and-branch duct systems that require precise directional terminations at floor, wall, or ceiling registers.\u003c\/p\u003e\u003cp\u003eThis boot is appropriate for new construction and retrofit duct installations where a 4-inch by 10-inch register opening is required. The left-hand orientation suits applications where the duct approaches the register from the right and must terminate on the left side of the boot. The 2-inch extension provides additional length to reach registers set deeper into a floor or wall cavity, reducing the need for separate extension collars in the run.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand end boot orientation for directional duct terminations\u003c\/li\u003e\n\u003cli\u003e4 inches x 10 inches main body fits standard 4x10 floor or wall registers\u003c\/li\u003e\n\u003cli\u003e6-inch neck size for connection to matching round duct\u003c\/li\u003e\n\u003cli\u003eIntegrated 2-inch extension eliminates need for a separate extension collar\u003c\/li\u003e\n\u003cli\u003ePurpose-built for trunk-and-branch residential supply duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for residential and light commercial HVAC duct systems requiring a 4-inch by 10-inch left end boot with a 6-inch neck connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal contractor.
