Summary

This is the ski service holder fastening a slalom ski on the multi-purpose workbench.
The holder will be fixed between the bench jaws at the distance of the ski binding (equal to ski boot's sole). The ski is then locked in to the table with the ski's binding, the ski-stopper goes away as well.

The set has also the connector between the end parts (adjustable for 220-330mm binding distance). With the connector you can first place the unit in to the ski and after that fasten the the ski in to the workbench. This will also make the unit more ridged but seems to work also with out.
