Air Flow Products 5241005 Straight Ceiling Diffuser Boot

Product Description

The AIR FLOW PRODUCTS 5241005 is a straight ceiling diffuser boot designed to connect ductwork to a ceiling diffuser in residential and light commercial HVAC systems. This boot transitions airflow from the supply duct to the diffuser face, distributing conditioned air into the occupied space. It measures 4 inches by 10 inches by 5 inches and is sized for compatibility with standard rectangular diffusers. HVAC installers and sheet metal contractors work with this type of fitting during new construction, renovation, or system retrofit projects where a straight-run ceiling diffuser connection is required.

This diffuser boot is suited for forced-air supply systems in residential and light commercial applications. It is installed at the ceiling plane where the supply duct terminates and the diffuser register mounts. The straight configuration is used when the duct runs perpendicular to the ceiling surface and connects directly to the diffuser without an offset. This makes it a common fitting in drop-ceiling and joist-bay duct installations.

Key Features

• Straight boot configuration for direct duct-to-diffuser connections
• 4 inches by 10 inches by 5 inches sizing for standard rectangular diffuser fitment
• Designed for ceiling-mount supply air applications
• Compatible with forced-air residential and light commercial HVAC systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard rectangular ceiling diffusers in residential and light commercial forced-air supply systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handling unit and close the supply damper before working on supply-side ductwork. Secure the boot to the duct collar using sheet metal screws and seal all joints with UL-listed duct sealant or foil tape per applicable mechanical codes. Ensure the diffuser face is flush with the ceiling surface after installation to prevent air bypass.
