Cool Shield RackFill blanking panels combine performance, versatility and low cost in one innovative solution.

RackFill blanking panels combine performance, versatility and low cost in one innovative solution. 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 rack spaces in literally seconds. RackFill panels are available in 1U to 27U sizes. 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 have allowed RackFill panels to achieve ASTM E84 highest Class A fire rating. In fact, the flame spread and smoke density rates are so low that they are also approved to be used in plenum spaces. There are no other blanking panel solutions available which can match the combination of features that RackFill offers.
