Conical Cable Operated Dampers
from Duro Dyne are now available!
Conicals not sold separately.
The Conical Cable Operated Damper Assembly allows for easy installation due to its self-stick double faced gasket which comes pre-applied to the flange.
Just peel, stick and fasten with sheet metal screws through the pre-punched drill holes. This eliminates the need to cut an exact hole and speeds up the installation process, while the gasket securely seals the connection after installation.

In addition to the ease of installation, the design of the conical damper greatly increases the efficiency of the air flow in the ductwork.
