8" Duct Board Top Takeoff

8" Duct Board Top Takeoff – Built for Secure and Efficient HVAC Connections

The 8-inch duct board top takeoff is engineered to provide a reliable transition from duct board plenums to branch ducts. Designed for professional HVAC applications, this component ensures a tight, efficient fit that helps maintain system performance and reduce air leakage. With its galvanized steel construction and reinforced features, it is well-suited for both residential and light commercial ductwork installations.

Key Advantages

• Precision-Fabricated Tabs – Bendable tabs allow for secure seating into duct board with minimal air loss.
• Riveted Construction – Adds strength and rigidity, preventing deformation under job site handling.
• Galvanized Steel Body – Manufactured from 30-gauge galvanized steel with G-30 coating for corrosion resistance and long service life.
• Optimized Airflow Design – Provides consistent airflow transition from main plenum to 8-inch branch ducts.
• Standard Sizing – Fabricated to industry dimensions for straightforward compatibility.

Technical Specifications

• Material: 30 ga galvanized steel, G-30 coated
• Base Size: 8" x 7"
• Height: 9-1/2"
• Connection Type: Tabbed, riveted construction
