HotLok Full Rack Blanking Panel Kit




Designed to seal up to 42U of opening in the server rack, the Full Rack Blanking Panel Kit greatly reduces bypass airflow by eliminating the gaps in the server rack and creating a contained server rack environment. This sealing solution increases usable cooling unit capacity, maximizing the effectiveness and efficiency of your cooling infrastructure.


  • Multiple U sizes (1U and 2U blanking panels; 3U, 9U and 12U blanking sheets) for a more flexible, reconfigurable blanking system
  • Two Kits – The 42U Kit of blanking space includes HotLok Blanking Panels or the 36U Kit of blanking space that does NOT include HotLok Blanking Panels
  • Adapts to existing HotLok Blanking Panels through the use of an engineered mechanical clip
  • Engineered mechanical clip design allows for a quick and simple installation
  • Can be re-used and re-configured as necessary
  • Utilizes ABS sheets that do not sag or require attachment to the rails (used for larger blanking areas)
