Underground network distributors (cable chambers) are part of every network infrastructure. The space requirements in underground network distributors and network stations are increasing. Network structure-relevant installations, built-in parts and bending radii of the media require sufficient space for optimal laying and use. For example, functions of above-ground network distributors (KVz) can be installed in underground network distributors (cable chambers) as required. All the advantages of the ROM-Box are essentially also implemented in the ROM-Box XL series. You benefit from the following clear XL dimensions: 100/100 cm 100/150 cm 100/200 cm Further dimensions are possible depending on the market or commercially available chamber covers.
