The invention generally comprises a blank panel for use with rack units. The blank panel comprises at least one face plate having a rectangular front plate surface, a back plate surface, top plate surface, bottom plate surface and two side plate surfaces. The face plate has a height corresponding to multiples of 1.75 inches. The face plate incorporates a means for slidably receiving fasteners. The blank panel further comprises fasteners with mating portions for being slidably engaged with the face plate, and fastening portions for being further attachable to a rack unit. The fasteners have varied geometry to accommodate rack units with alternate configurations. The blank panel further comprises a plurality of face plates attached along the top and bottom plate surfaces. Each of the face plates is capable of individually receiving fasteners. The individual face plates of the blank panel are also modular and can be separated to configure the blank panel to varied height requirements.
