Air Flow Products 84DB05 Duct Board Tab Takeoff 5 in

Product Description

The AIR FLOW PRODUCTS 84DB05 is a duct board tab takeoff fitting designed to create branch connections in fiber glass duct board systems. This fitting attaches to the main duct board trunk and allows a branch duct run to be tapped off cleanly and securely. The tab design locks into the duct board material to maintain a firm connection and an airtight transition. At 5 inches in diameter, it suits common residential and light commercial branch duct sizing. HVAC technicians and sheet metal installers use this fitting during new duct system fabrication and retrofit work.

This fitting is used in residential and light commercial HVAC duct systems built with fiber glass duct board. It is suited for supply air distribution applications where a branch takeoff is needed from a rectangular duct board trunk. The tab takeoff style is a standard installation method in duct board construction, providing a positive mechanical connection without additional fasteners in most applications.

Key Features

• 5-inch diameter branch opening for standard residential duct sizing
• Tab-style attachment designed for secure engagement with fiber glass duct board
• Provides a clean, airtight branch connection from a duct board trunk line
• Supports supply air distribution in low-pressure duct systems

Compatibility

Designed as an OEM-style fitting for use with fiber glass duct board trunk systems requiring a 5-inch branch takeoff connection.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified duct fabricators. The system should be de-energized and airflow shut down before any duct modifications are made. Fitting installation into duct board should follow NAIMA and SMACNA duct board fabrication guidelines. Seal all connections with listed duct tape or mastic sealant per local mechanical code requirements.
