GRUNDOMAT Technical Data

The pictured machines can be equipped either with a crowned head or a stepped head.The short versions are especially suitable for property service connections as they are shorter and lighter than the standard versions. The connection pits are smaller and handling is easier.

To achieve shorter construction lengths, the NK machines are equipped with a rigid head.
