19"/1U Universal Rackmount Unit for non 19" units like e. g.: RME Multiface, Multiface II, Quadmic, ADI-2, Fireface 400, ADI-4 DD and many other units. We updated some of the drill-hole's positions, reduced weight, removed rear "teeth". The sheet material is much leaner than at the MK-I version. The oplong slits on the back are designed to be used as strain-relief by using cable-straps, the ones before can be used to mount e. g. AC-adaptors on the UNIRACK 19/II.
