Air Flow Products 84DB1510 Duct Board Tab Takeoff

Product Description

The AIR FLOW PRODUCTS 84DB1510 is a duct board tab takeoff fitting designed for use in low-pressure sheet metal and duct board distribution systems. This fitting provides a branch connection point where a round collar or flex duct run connects to a main duct board trunk. The 10-inch diameter opening and 1.5-inch tab depth make it a standard-size component for residential and light commercial HVAC applications. HVAC installers use this type of fitting to maintain consistent airflow routing while keeping labor time low during rough-in work.

This takeoff is suited for residential and light commercial forced-air systems where duct board is the primary trunk material. It is used at the point where a branch run departs the main supply trunk, allowing the installer to punch or cut an opening in the duct board and secure the fitting with the integrated tab flange. The 84DB series designation indicates compatibility with standard 1.5-inch duct board panels commonly used in new construction and retrofit supply systems.

Key Features

• 10-inch collar diameter for standard branch run connections
• 1.5-inch tab depth sized for standard duct board panel thickness
• Tab-style flange design seats and locks into duct board without additional hardware
• Designed for low-pressure forced-air supply duct applications
• Compact profile supports efficient branch layout in tight plenum or attic spaces

Compatibility

Designed as an OEM-style replacement and new-installation fitting for duct board trunk systems using standard 1.5-inch duct board panels.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics during ductwork rough-in or repair. Power down the air handler and shut off the system before cutting into any pressurized duct section. The fitting tab is inserted through a field-cut opening in the duct board face and folded against the board interior to secure the connection. All connections should be sealed with listed duct board mastic or foil tape per local mechanical code requirements.
