Air Flow Products 84DB10 Duct Board Tab Takeoff 10 in

Product Description

The AIR FLOW PRODUCTS 84DB10 is a duct board tab takeoff fitting designed for connecting branch ducts to main duct board trunk lines. This fitting uses a tabbed design that seats securely into duct board material, providing a clean, repeatable connection point for round branch runs. At 10 inches in diameter, it is sized for medium-capacity residential and light commercial supply air distribution systems. HVAC installers and sheet metal mechanics use this fitting during new construction ductwork fabrication and system retrofits where duct board trunk lines are specified.

This takeoff is intended for use in forced-air HVAC systems where duct board is the primary trunk material. It is well-suited for residential new construction and light commercial applications where low-profile, insulated duct systems are required. The tab design allows the fitting to be installed without sheet metal screws at the trunk connection, simplifying the fabrication process for crews working with duct board.

Key Features

• 10-inch diameter sized for medium-volume branch supply runs
• Tab design locks into duct board trunk without additional fasteners at the connection point
• Compatible with standard duct board fabrication methods used in residential and light commercial HVAC work
• Provides a consistent, repeatable branch takeoff connection for duct board trunk systems

Compatibility

Designed as an OEM-style replacement and standard fitting for duct board trunk-and-branch forced-air distribution systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic familiar with duct board fabrication practices. Power down the air handling unit and shut off the system before cutting into or modifying existing ductwork. Follow local mechanical codes and SMACNA duct construction standards for sealing, support, and clearance requirements. Seal all connections with a listed duct sealant or UL 181-rated tape appropriate for duct board applications.
