19″ RackFill Blanking Panel Full Rack Kits

Rackfill Blanking Panels

RackFill Full Cabinet Blanking Kits are the ideal solution for sealing unused server cabinets. Sealing unused cabinets to maintain desired airflow patterns in hot aisle/cold aisle layouts and especially in contained aisles. The panels combine performance, versatility and low cost in one innovative solution. RackFill panels can ship with your choice of three mounting options:

  1. Push-in clips for round hole (telecom) mounting rails
  2. Push-in clips for industry standard square hole mounting rails
  3. Ultra-thin high-performance magnetic discs which will adhere to any steel mounting rails.

All options allow data center managers to quickly install lightweight yet rigid panels to fill empty cabinets in literally seconds. All panels feature perforated scores in 1U increments to allow the panels to be quickly and accurately cut to any size needed as hardware is added. Panels can be cut in seconds with a common utility knife or scissors. Specially formulated plastic resins allow Rack Fill panels to achieve ASTM E84 highest Class A fire rating.
