Air Flow Products 5241206 Straight Ceiling Diffuser Boot

Product Description

The AIR FLOW PRODUCTS 5241206 is a straight ceiling diffuser boot designed for use in residential and light commercial forced-air HVAC systems. This fitting connects ductwork to a ceiling-mounted diffuser or register, directing conditioned air from the supply trunk into the occupied space. The boot measures 4 inches by 12 inches by 6 inches, making it a standard-profile unit suited for typical ceiling plenum depths. HVAC installers and sheet metal contractors specify this type of boot during new construction and retrofit applications where a clean, straight-run termination at the ceiling plane is required.

The 5241206 straight ceiling diffuser boot is used in forced-air supply systems where the duct run approaches the ceiling register from directly above without an offset or angle transition. It is appropriate for residential new construction, light commercial tenant improvements, and retrofit duct system work. The straight configuration simplifies installation in open-joist ceiling assemblies and dropped ceiling grids where clearance is not a limiting factor.

Key Features

• Straight-run design eliminates offset transitions for simplified ceiling installations
• 4 x 12 x 6 inch profile fits standard supply register openings and typical plenum depths
• Compatible with conventional residential and light commercial forced-air supply duct systems
• Designed for ceiling-mount orientation with standard diffuser or register attachment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial forced-air ceiling supply systems using standard 4 x 12 inch register openings.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Shut down the air handling unit and confirm the system is depressurized before connecting or sealing the boot. Secure the boot to the duct and register frame using sheet metal screws and approved duct sealant or mastic in accordance with local mechanical codes. Confirm the ceiling opening dimensions match the boot face before cutting to avoid oversizing the register cutout.
