The stack holder is mounted on the stone transportation clamp. This stack holder was developed for keeping the stacked stones in place during transport. To prevent the stones from falling forward in case you reverse suddenly, you can attach this stack holder to your stone transportation clamp. It operates hydraulically and is controlled from the Rollmops or Knikmops.
