The tunnel set medium consists of 4 tunnel plates, fixing set extension (8 pieces), 1 piece of foam rubber strip for sealing the separate tunnel-plates and an extension for the connection cable.

The tunnel plates have a grey and a white side. The tunnel can therefore be designed grey or white. Our experience has shown that it is quite advantageous to design a grey base plate due to sensitivity to dirt, the white side walls make the tunnel appear brighter.
