Air Flow Products 84DBD10 Duct Board Tab Takeoff 10 in

Product Description

The AIR FLOW PRODUCTS 84DBD10 is a duct board tab takeoff fitting with an integrated damper, designed for use in low-pressure residential and light commercial duct distribution systems. This fitting connects branch runs to duct board main trunks using a tab-style mechanical attachment, eliminating the need for sheet metal screws at the collar. The built-in damper allows the installer to balance airflow at the takeoff point without adding a separate balancing damper downstream. HVAC technicians and sheet metal installers working with fiberglass duct board systems will find this a direct, field-ready component for new construction and retrofit applications.

The 84DBD10 is sized at 10 inches and is suited for branch takeoff connections in forced-air heating and cooling systems built around duct board trunks. It is commonly installed in residential construction where duct board is specified for its thermal and acoustic performance. The tab design seats into the duct board surface and is secured with standard duct board construction techniques, making it compatible with typical field assembly workflows on both horizontal and vertical trunk runs.

Key Features

• Integrated damper allows on-site airflow balancing at the takeoff without additional hardware
• Tab-style attachment designed specifically for duct board trunk installations
• 10-inch collar size fits standard branch duct connections in residential and light commercial systems
• Eliminates the need for a separate balancing damper in the branch run
• Field-ready design supports straightforward installation during new construction or retrofit

Compatibility

Designed as an OEM-style replacement and new-installation fitting for duct board trunk-and-branch forced-air distribution systems where a 10-inch tab takeoff with damper is required.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers familiar with duct board fabrication practices. The air handling system should be powered down and the blower confirmed off before cutting into an existing duct board trunk. Tab takeoffs require proper sealing at the collar interface with approved mastic or FSK tape per local mechanical codes. Do not overtighten or force the tab tabs into duct board material, as fiberglass board is susceptible to crushing that can compromise the seal.
