16-640-03

From now on only available for service purposes.

This external unit can be very easily built into a wall or partition and provides space for 3 modules. It does not include a letter box. 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.
