The AIR FLOW PRODUCTS 7241005 is a center end register boot designed to transition ductwork to a floor, wall, or ceiling register opening. This 90-degree boot connects round or rectangular supply duct to a register face, directing conditioned air into the living space. It is sized at 4x10x5 inches, making it a common fit for residential HVAC supply runs. HVAC installers and sheet metal contractors use this boot during new construction and retrofit duct installations where a center end outlet configuration is required.
This register boot is suited for residential forced-air heating and cooling systems. The center end design positions the register opening at the end and center of the boot, which is typical for floor register applications and certain wall-drop installations. It is used in trunk-and-branch duct systems where supply air is distributed through individual branch runs terminating at a register boot and grille assembly.
Designed as an OEM-style replacement or new-installation component for residential forced-air HVAC duct systems requiring a 4x10x5 inch center end register boot with a 90-degree configuration.
Register boots are installed by licensed HVAC technicians or sheet metal contractors. Shut down the air handling system before connecting or replacing a boot in an active duct system. Boots should be sealed at all seams and joints with mastic sealant or UL-listed foil tape in accordance with local mechanical codes. Secure the boot to surrounding framing or duct board per standard installation practice before attaching the register grille.
