Product Description

The AIR FLOW PRODUCTS 5340805 is a ceiling diffuser boot with rail designed for residential and light commercial HVAC duct systems. This boot connects the ductwork to a ceiling diffuser, directing conditioned air into the occupied space. The unit features a 4x8 inch rectangular opening and a 5 inch round collar for duct connection. HVAC installers and sheet metal contractors use this component during new construction and renovation work to terminate supply duct runs at the ceiling plane.

This ceiling diffuser boot is suited for supply air applications in residential homes and light commercial spaces. It is installed at the end of a branch duct run where a ceiling diffuser or register is required. The 4x8 inch face dimension pairs with standard 4x8 ceiling diffusers, and the 5 inch collar accepts round flexible duct or rigid round ductwork of the same diameter.
