Air Flow Products 84DB14 Duct Board Tab Takeoff 14 in

Product Description

The AIR FLOW PRODUCTS 84DB14 is a duct board tab takeoff fitting designed for branch connections in fibrous glass duct board HVAC systems. This 14-inch takeoff installs at the main trunk or plenum to redirect conditioned airflow into branch runs, providing a secure, tab-locked connection without the need for sheet metal cutting tools. It is a standard component in low-pressure residential and light commercial air distribution systems. HVAC technicians and sheet metal installers work with this fitting during new construction and system modification projects.

This takeoff is used in fibrous glass duct board installations where branch taps are needed along the main supply or return trunk. It suits residential forced-air systems and light commercial applications where duct board is the primary distribution material. The tab design allows the fitting to lock into a scored and folded opening in the duct board panel, creating a connection point for flexible duct or additional duct board branch runs.

Key Features

• 14-inch diameter tab takeoff sized for standard branch connections in duct board systems
• Tab-style retention locks the fitting into the duct board opening without separate fasteners
• Designed for use with fibrous glass duct board trunk and plenum sections
• Compatible with flexible duct connections at the branch outlet
• Part of the 84DB series for consistent fitment across multiple sizes

Compatibility

Designed as an OEM-style replacement and new-installation fitting for fibrous glass duct board HVAC distribution systems requiring 14-inch branch takeoff connections.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics. Shut down the air handling unit and confirm the system is depressurized before cutting into an existing trunk or plenum. Score and fold the duct board opening to the correct dimensions before inserting and locking the tab takeoff. Seal all connections with UL 181-rated tape or mastic per local mechanical code requirements.
