Grille Collar Dampers offer an effective and space-saving solution for airflow regulation at terminal outlets. Constructed from high-quality aluminum, these dampers are lightweight, corrosion-resistant, and easy to install. They are typically mounted at the neck of grilles and diffusers and feature adjustable blades or dampening mechanisms that allow precise control over air volume entering or exiting a space. The collar design allows for easy integration with ductwork, making it ideal for both new installations and retrofit applications. These dampers are particularly useful in ceiling or wall-mounted air distribution systems where accessible airflow control is needed without altering duct layout.
