The CD60 Control Damper has been upgraded to meet or exceed requirements for the most extreme applications. The expanded CD60 series includes a stainless-steel option with the same airfoil-blade profile. CD60 features facilitate ease of installation and the ability for customization and flexibility for most commercial applications. The patented single-piece frame utilizes mechanical clinching at 24 locations, making it 40 percent stronger than its predecessor and the strongest in the industry. This results in quick and easy installation, eliminating racking and subsequent leakage issues.
