From now on only available for service purposes.

This external unit can be very easily built into a wall or partition. You can add 2 more modules to this letter box. It is equipped with a letter box which is emptied from the rear. The front plate is made of brushed, anodised aluminium. The size of the body of the unit depends on the number of flush-mounting modules required. A maximum of eight modules can be flush mounted. The LED module is supplied standard. Would you like the external unit in a non-RAL colour? Then order the following reference number: 16-640-99 (without flush-mounting letter box) or 16-641-99 (with letter box). In this case your order must be accompanied by a complete and signed custom-work document. The custom-work document can be found as an appendix to the price list and catalogue. One is also available upon request from Niko.
