The HotLok Blanking Panel is a snap-in blanking panel that provides an effective seal in IT equipment cabinets and helps you identify hotspots within minutes of installation. The state-of-the-art technology controls airflow for optimized cooling effectiveness. It reduces hotspots and bypass airflow by preventing equipment exhaust air or hot aisle air from circulating to the conditioned air-intake stream in front of the cabinet. The HotLok Blanking Panel is also available with a HotLok Temperature Strip which helps you identify intake temperatures. This product is available in 1U and 2U models, with or without HotLok Temperature Strips.
