Air Flow Products 84AT05 Airtight Takeoff Flat Duct 5 in

Product Description

The AIR FLOW PRODUCTS 84AT05 is an airtight stick-on takeoff designed for use with flat duct systems. This fitting creates a branch connection off a flat duct run and uses an adhesive-mount design that eliminates the need to cut and frame a traditional collar opening. The airtight construction minimizes conditioned air loss at the takeoff point, helping maintain system efficiency. With a 5-inch collar diameter, this fitting suits residential and light commercial HVAC duct branches. HVAC installers and sheet metal contractors are the primary users.

This takeoff is used in low-pressure supply air duct systems where flat duct is the primary distribution method. The stick-on design makes it well suited for retrofit and new-construction applications where speed of installation and duct integrity are both priorities. The 5-inch size is a common branch diameter for individual room supply runs off a flat trunk line.
