Air Flow Products 84DB07 Duct Board Tab Takeoff 7 in

Product Description

The AIR FLOW PRODUCTS 84DB07 is a duct board tab takeoff fitting designed for use in low-pressure air distribution systems. This fitting allows HVAC installers to branch supply air from a main duct board trunk to individual supply runs. The 84DB07 is sized at 7 inches, making it compatible with standard round duct transitions off duct board plenums and trunk lines. It is installed as part of a sheet metal and duct board system in residential and light commercial HVAC applications where duct board is the primary trunk material.

This takeoff fitting is used where a supply branch needs to be tapped into a duct board trunk or plenum. The tab design secures the fitting directly to the duct board surface without the need for additional brackets in most installations. It is a common component in new construction HVAC duct systems as well as duct modification and replacement projects. HVAC sheet metal mechanics and duct installers work with this fitting during rough-in and duct fabrication phases.

Key Features

• 7-inch round opening sized for standard flexible or rigid duct connections
• Tab design allows direct attachment to duct board surface
• Sized for low-pressure residential and light commercial supply air systems
• Compatible with duct board trunk and plenum construction methods

Compatibility

Designed as an OEM-style replacement and new-installation fitting for duct board supply air systems requiring a 7-inch round branch takeoff connection.

Installation Notes

Installation is performed by licensed HVAC mechanics or trained duct fabricators. Power down the air handling unit and confirm the system is de-energized before working on any connected ductwork. Secure the tab flanges to the duct board surface using approved duct board adhesive and mechanical fasteners per local mechanical code requirements. All duct connections should be sealed with listed duct sealant or approved tape in compliance with applicable energy codes.
