Air Flow Products 84AT16 Stick-on Takeoff Flat Duct 16in

Product Description

The AIR FLOW PRODUCTS 84AT16 is an airtight stick-on takeoff fitting designed for flat duct systems. It provides a sealed branch connection point on flat ductwork, allowing conditioned air to be directed from the main trunk line to a branch run. The adhesive-backed design simplifies installation by eliminating the need for mechanical fasteners at the attachment point, reducing air leakage at the connection. HVAC technicians and sheet metal installers use this fitting on residential and light commercial duct systems where airtight performance is required at each takeoff location.

This takeoff is sized at 16 inches and is intended for use on flat duct configurations. It is suited for low-pressure supply or return air distribution systems where a secure, sealed branch connection must be made directly to the duct surface. The stick-on design makes it practical in tight installations where conventional collar fittings are difficult to seat and seal properly.

Key Features

• Airtight construction minimizes conditioned air loss at branch takeoff points
• Stick-on adhesive backing allows direct attachment to flat duct surface without additional fasteners
• 16-inch size accommodates larger branch duct connections in residential and light commercial systems
• Flat duct compatible design for use on rectangular trunk lines and plenums

Compatibility

Designed as an OEM-style replacement and new-installation fitting for flat duct HVAC distribution systems requiring airtight branch takeoff connections.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified sheet metal mechanic. Before installing, shut down the air handling unit and confirm the duct surface is clean, dry, and free of dust or oils to ensure proper adhesion. Work should comply with local mechanical codes and SMACNA duct construction standards. Avoid applying the fitting to damaged or deformed duct surfaces, as an uneven substrate will compromise the airtight seal.
