The CPI Containment Floor Front Seal Kit is used at the bottom of cabinets to seal the space between the bottom of the cabinet and the floor when leveling feet or casters are in use. Eliminating this source of bypass airflow is essential due to the high pressure typically experienced in this area. It is compatible with F-Series TeraFrame® Gen 3 cabinets, GF-Series GlobalFrame® Gen 2 cabinets and N-Series TeraFrame® Gen 3 cabinets.
