The boot measures 8 inches by 4 inches at the register face and transitions to a 5-inch round collar, making it a standard choice for branch takeoffs in forced-air supply systems. Constructed for a secure, low-leak fit, the flanged perimeter seats flush against finished flooring, ceilings, or wall surfaces. HVAC installers and sheet metal contractors use this boot when terminating supply runs at floor, ceiling, or sidewall register locations.\u003c\/p\u003e\n\u003cp\u003eThis boot fits supply air distribution systems where a 5-inch round duct feeds an 8-inch by 4-inch register opening. The 202RF series is produced in multiple sizes to serve a range of round duct diameters, including 5-inch, 6-inch, 7-inch, 8-inch, and 9-inch round duct connections. It is suited for new construction and retrofit applications in ducted forced-air heating and cooling systems where a flanged boot is required for a clean register mounting surface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCenter-end configuration routes round duct into the end of the boot, with the register face centered on the opposite side\u003c\/li\u003e\n  \u003cli\u003eIntegral flange provides a flat mounting surface for standard floor, ceiling, or wall registers\u003c\/li\u003e\n  \u003cli\u003e8-inch by 4-inch register face opening accepts standard sized grilles and registers\u003c\/li\u003e\n  \u003cli\u003e5-inch round collar connects directly to 5-inch round supply duct\u003c\/li\u003e\n  \u003cli\u003eLightweight at 1 pound for easy single-technician handling during installation\u003c\/li\u003e\n  \u003cli\u003eAvailable across 8 popular sizes to support multiple round duct diameters in the same product family\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction component for ducted forced-air HVAC systems requiring a center-end flanged register boot with a 5-inch round collar and an 8-inch by 4-inch register face opening.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handling unit at the disconnect before working in the duct system.
