The Decksaver DS-PC-RANE4 cover is a polycarbonate-shelled, custom-moulded cover that was designed specifically to match the RANE FOUR DJ Controller's distinctive contours. Your RANE FOUR DJ Controller will be shielded from dust, spills, and other forms of incidental damage by the cover, which also allows you unobstructed access to the device's inputs and outputs at all times.
