These Original FACTORY equipment heavy duty rack ears are completely powder-coated with the exact same black finish as your ULN-8 or LIO-8. Made of solid steel, the rack ears will safely support your unit in any standard 19" rack whether in your studio or on the road. Each kit comes with a set of black stainless steel mounting screws and 4 rubber feet which can be used on the bottom of the unit when it is out of the rack.
