The HotLok® Blanking Panel is a next-generation blanking panel that reduces hotspots and bypass airflow by preventing equipment exhaust air or hot-aisle air from migrating to the conditioned air-intake stream at the front of the cabinet.

The HotLok Blanking Panels are a green solution for energy consumption savings and reducing the carbon footprint of data centers.
