Air Flow Products 84AT12 Stick-on Takeoff Flat Duct 12in

Product Description

The AIR FLOW PRODUCTS 84AT12 is an airtight stick-on takeoff designed for flat duct systems. It provides a sealed branch connection point directly on flat ductwork, allowing a technician to add or extend a supply or return air run without cutting into the main trunk with traditional fittings. The airtight design limits conditioned air loss at the connection point, maintaining system efficiency. This fitting is sized at 12 inches and is installed by HVAC technicians during new duct installations or duct modification work.

This takeoff is suited for residential and light commercial HVAC duct systems that use flat duct configurations. It is commonly installed in attic runs, crawlspace duct systems, and utility spaces where flat duct is the standard trunk format. The stick-on attachment method allows placement at any point along the flat duct surface, giving installers flexibility when laying out branch runs without requiring welded or flanged connections.

Key Features

• Airtight construction limits conditioned air leakage at the branch connection
• Stick-on attachment method allows field placement anywhere along flat duct surface
• 12-inch size accommodates standard branch duct runs
• Designed for flat duct applications common in residential and light commercial systems
• Eliminates the need for traditional cut-in fittings during branch additions

Compatibility

Designed as an OEM-style replacement and new-installation fitting for flat duct systems in residential and light commercial HVAC applications.

Installation Notes

Installation is performed by a licensed HVAC technician. The HVAC system should be powered down and the air handler shut off before any ductwork modification. The duct surface should be clean and free of debris before applying the stick-on fitting to ensure a proper airtight seal. Local mechanical codes and ASHRAE duct leakage standards should be referenced when adding branch takeoffs to an existing system.
