The SKB-4 shares the width of the SKB-2 but is deeper, so it takes 12 × 20 l, 8 × 30 l or 4 × 50 l kegs. Like the rest of the SKB range it is built from panels and arrives flat-packed, which allows assembly in a cellar or other confined space. No cooling unit is included: the SKB-MU mounts on top, the SKB-MU 50 R on the right-hand side, and the cut-outs for either are already made.
Both units provide fan-assisted cooling, an electronic thermostat and automatic defrost. A reinforced base plate and two large solid doors make loading and unloading kegs easy; the legs adjust from inside. Finished in anthracite outside and silver inside, it has no lock or lighting.
Net volume is 840 litres from 857 litres gross, the external size of 1060 × 975 × 1080 mm encloses an interior of 980 × 895 × 950 mm, and the cabinet weighs 105.5 kg net.
