Advanced version of EC-series. At each mount location, a tube made from Carbon Fiber Reinforced Polymer (CFRP) links the top and bottom plate.

The tubes allow easy cleaning of the board, installation of removable additional mounts on the bottom side, tuning of natural frequencies and vibration damping by inserting adaptive elements.
