Air Flow Products 84DB1507 Duct Board Tab Takeoff

Product Description

The AIR FLOW PRODUCTS 84DB1507 is a duct board tab takeoff fitting used in low-pressure duct distribution systems. It connects branch ducts to a main duct board trunk, allowing supply air to be directed from the primary ductwork to individual supply runs. The tab-style design seats into duct board material and creates a secure, sealed connection point. This fitting is typically installed by HVAC technicians during new construction duct fabrication or duct system replacement work. Key dimensions are 7 inches and 1.5 inches, fitting standard duct board trunk applications.

This takeoff is suited for residential and light commercial HVAC installations where duct board trunk systems are used. It is most commonly applied in low-pressure supply air distribution, where branch runs must be tapped off the main duct board plenum or trunk line. The tab design allows for a flush, secure fit into the duct board surface without requiring additional fasteners in typical installations.

Key Features

• Tab-style takeoff design seats directly into duct board material for a secure fit
• 7-inch size accommodates standard branch duct connections
• 1.5-inch tab depth provides positive engagement with duct board trunk walls
• Compatible with low-pressure supply air duct distribution systems
• Simplifies branch connection during duct board fabrication and installation

Compatibility

Designed as an OEM-style fitting for use with duct board trunk systems in residential and light commercial low-pressure HVAC supply air distribution applications.

Installation Notes

Installation is performed by licensed HVAC technicians as part of duct board system fabrication. The air handling unit or furnace should be shut off and the system depressurized before cutting into any existing duct trunk. Use appropriate duct board cutting tools and seal all connection points with approved foil tape or duct board adhesive per local mechanical code requirements. Follow SMACNA duct construction standards and local jurisdiction guidelines for low-pressure duct systems.
