Circular fire damper cartridges SC+ are designed to be installed in the wall penetrations of circular ducts. In the event of a fire, they stop the spread of fire through the duct. The different models of cartridges (SC+60, SC+90, and SC+120) have the same characteristics, differing only in their fire resistance classification of 60, 90, or 120 minutes.
