Airflow Management Blanking Panels promote proper airflow within a rack enclosure by occupying unused space. Schneider Electric offers several varieties for differing rack management requirements. Modular toolless blanking panels allow for quick and easy installation into any EIA-310 19 inch rack or enclosure with square mounting holes. Metallic blanking panels are for threaded rail applications. Brush strips provide a barrier to airflow, while allowing cables to be passed from the front to the rear of the rack.
