Air Flow Products 84DB1506 Duct Board Tab Takeoff

Product Description

The AIR FLOW PRODUCTS 84DB1506 is a duct board tab takeoff designed for use in fibrous glass duct board HVAC systems. This fitting connects a branch duct run to a main duct board trunk, allowing conditioned air to be distributed to individual zones or supply outlets. The 84DB1506 features a 6 inch diameter opening and a 1.5 inch tab depth, providing a secure mechanical attachment point when inserted and tabbed into duct board material. Installation is typically performed by sheet metal or HVAC technicians during new construction or duct system retrofits.

This tab takeoff is suited for residential and light commercial HVAC duct systems built with fibrous glass duct board. It fits into a matching cutout in the duct board and is secured using the integral tab system, eliminating the need for additional fasteners at the connection point. It is commonly used where branch takeoffs are required along a main supply trunk constructed from rigid duct board panels.

Key Features

• 6 inch diameter opening for standard branch duct connections
• 1.5 inch tab depth for positive engagement with duct board material
• Tab-style attachment designed specifically for fibrous glass duct board systems
• Provides a reliable, low-leakage transition from trunk to branch duct

Compatibility

Designed as an OEM-style replacement and new-installation fitting for fibrous glass duct board HVAC trunk and branch systems.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable mechanical codes. Power down the air handling unit and close the supply dampers before cutting into an active duct system. The takeoff tab must be fully seated and folded against the duct board surface to ensure a proper, low-leakage connection. Seal all joints with UL 181B-rated tape or mastic as required by local code.
