Air Flow Products 5341005 Ceiling Diffuser Boot 4x10

Product Description

The AIR FLOW PRODUCTS 5341005 is a ceiling diffuser boot with rail designed for residential and light commercial HVAC duct distribution systems. This boot transitions from round duct to a rectangular diffuser opening, directing conditioned air into the occupied space through a ceiling-mounted register or diffuser. The unit features a 4x10 inch face opening and a 5 inch round collar for duct connection. It is installed by HVAC technicians and sheet metal contractors as part of supply air trunk-and-branch or plenum-based distribution layouts.

This ceiling diffuser boot is suited for new construction and retrofit applications where a ceiling register or diffuser is fed from a round flex duct or rigid round branch. The 5 inch collar accommodates standard 5 inch round duct connections, and the 4x10 inch opening matches widely used residential register sizes. The rail design supports secure registration of the diffuser or register face, keeping the assembly flush and stable in the ceiling plane.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling system before connecting ductwork or securing the boot in the ceiling cavity.
