The infinite positioning possibilities of the telescopic lip makes the Stertil X series ideal for loading or unloading end loads, where traditional swing lip dock levellers can be problematic. The unique rear hinge is of a closed type construction, leaving no gaps between the deck and the rear hinge.

Both the deck and the lip have a long chamfer. The ends of each chamfer are 2mm thick to ensure a smooth transit between dock and vehicle. The many features and options make the X series suitable for the most demanding customer.
